I love Scylla so much

hi!!! i'm assuuuuming you're talking about the effect in this one?

i'm using something called parallax mapping!! i know most people know what parallax is and how it works in the realworld but im just gonna demonstrate it real quick just so i dont have to keep going "ok now imagine how parallax works"

so imagine you have two windows. in the middle of the window on the left, there is an Orb. it is directly in the middle of the window. the window on the right also has an Orb, but this one is pushed backwards outside the window quite a bit. now if you look at the two windows, and turn them, you get this:

for the first window, the Orb stays basically in the center of the window. but in the second window, if you turn the window right, the Orb "looks like" it's moving left

parallax mapping is essentially taking this assumption, that if you change the angle you are looking at an object, the further away an object is, the more it will move in the opposite direction. i will spare you on the matrix math involved but you can get the exact relation you need by getting the Tangent Space View Direction. you dont need to understand the math behind this to use it

so, lets go back to the window example, how would you make the same effect, but with just this 2d texture of the Orb?

what if, whenever the object it was attached to turned right, you just moved the texture to the left, by X amount, where X is how far into the window the orb is. you would essentially be cheating god and "faking" the parallax. it would look like it's moving like it's far out of the window, but really, it's still a 2d texture. it would look like this:

i was too lazy to make the shader and record another gif but i dont need to because functionally it would look almost identical because when you turn it right the Orb moves left

again, you can just Know the right direction to push the texture in based on the current angle by getting the Tangent Space View Direction. ok another example. what if you had a black and white noise texture, like this

now what would happen if, instead of moving the whole texture X amount. you moved each pixel a proportional amount based on how bright it is. a 100% black pixel would not get moved at all, and a 100% white pixel would get moved the furthest along the Tangent Space View Direction. a pixel thats right down the middle would move half that distance etc etc. well it would look something like this!!!

thaaat's the basics behind it!!! it's also used for effects like faking room interiors through windows with just a 2d texture in biig cityskapes and the like

you can see how the cube example looks kind of like an ice cube with the distortion, that's Not intentional and how parallax mapping artifacts. i do not care about it, because i make crystals. but some people do care about it, so you can use parallax occlusion mapping, which is like parallax mapping but a step up

here's some more reads on it if you are interested!!!

A cool paper I've read recently is Morgan G. Ames' Charismatic Technology. In this one, she proposes the concept of Charismatic Technology as an explanation for the holding power that some technologies exhibit for long periods of times, even if they fail to deliver on their promises time and time again. The paper is written with a focus on the One Laptop Per Child (OLPC) project, which had the XO laptop as a figurehead:

The idea behind the project was that you would have this very promising laptop, with very promising features, such as:

• a hand crank for charging it (which never existed aside from a prototype, and all actual laptops were charged with AC power)
• two antennae "ears" also acted as latches and anthropomorphized the laptop (the antennae actually replaced the hand crank)
• a "view source" keyboard button that was considered revolutionary (it often did not work, also browsers had that feature for a while already)
• accessible and easy-to-repair hardware (cost-cutting and compromises made this unattainable and laptops were plagued with breakage)
• innovative screens that can be swivelled and flattened with its backlight off like an ebook (the screen was the second most common component to break and second most expensive to fix)
• a mesh network that can work without access point (which would grind the laptops to a halt if too many laptops connected and which was later dropped as a feature)
• an announced cost of $100 per device (a price never met, the lowest price point being $188)
• an objective of hundreds of millions of laptops across the world (roughly 2.5 million were used, mostly in Latin America)

The laptop meeting none of these objectives didn't matter. In fact, the media even added more to it, with stories of the laptop screen being the only light in a village (even though it functioned on AC power). So the author—who also spent 7 months of field work for an OLPC project—basically asks why is it that technologies like these keep captivating their users and admirers for decades, even when they never deliver on their promises?

That's where the idea of charismatic technology comes in:

[...] a charismatic object derives its power experientially and symbolically through the possibility or promise of action: what is important is not what the object is but what it promises to do. Thus, the material form of a charismatic technology is less important than how it invokes the imagination. [...] A charismatic technology’s promises are likewise uncannily compelling, evoking feelings of awe, transcendence, and connection to a greater purpose.

[...] Charisma moreover implies a persistence of this compelling force even when an object’s actions do not match its promises – hence the magical element of charisma.

[...]

In their often utopian promises of action, charismatic technologies are deceptive: they make both technological adoption and social change appear straightforward instead of a difficult process fraught with choices and politics. This gives charismatic technologies a determinist spirit, where technological progress appears natural, even inevitable.

This is a bit of an abstract definition (and the paper goes to greater length to couch it in literature), but clear enough for its purposes. Ames then dives into a deeper analysis that points out that even though charismatic technology promises to change its users' sociotechnical experience for the better, it always remains fundamentally conservative as a technology. Do note here that the author means conservative in terms of "maintaining existing values" rather than the political movement in the US:

a charismatic technology’s appeal is built on existing systems of meaning-making and largely confirms the value of existing stereotypes, institutions, and power relations. This unchallenging familiarity is what makes a charismatic technology alluring to its target audience: even as it promises certain benefits, it simultaneously confirms that the worldview of its audience is already ‘right’ and that, moreover, they are even savvier to have this technology bolster it.

This brings the concept into the ideological realm, which tends to ignore all contingencies and historical context, which makes whatever the ideology is about look like it stands outside of history, both inevitable and natural.

For the OLPC project, Negroponte and Papert are pointed out as leaders:

Both Negroponte and Papert are themselves charismatic, and both used it to build the charisma of the OLPC project and the XO laptop. While Negroponte has been the public face of the project, glibly flinging XOs across stages at world summits to demonstrate their ruggedness and talking about “helicopter deployments” of laptops to remote areas, Papert was the project’s intellectual father. His whole career focused on the idea of computers for children, leading to the development of LOGO, Turtle Graphics, Lego Mindstorms, and, finally, One Laptop per Child. [...] Papert is still often considered a central figure in education and design, and his books remain foundational to the curriculum at the MIT Media Lab.

The paper points out both leaders had the dream to change the world, to make it better, but also—as the author asserts—to make it in their image. This is based on three elements: childhood, schools, and computers.

For childhood, the OLPC project buys into the idea that children are born curious and only need the right context (eg. a laptop) to keep it going. This, however, assumes that engineering-oriented tinkering is a natural inclination, a common pattern in the history of American toy-making, along with ideas of healthy rebellion particularly in males ("boys will be boys"), which many features of the laptop reflected. The author mentions that this point of view tended to neglect other parts of childhood that are significant, such as household instability or food insecurity, and ignored these complex elements by universalizing children as 'yearners'.

Basically, project members assumed that their own childhoods were generalizable, and that the traits they showed in their largely white middle-class Americans, would show up in other 'intellectually interesting' children.

This extended with schooling. Papert, for example, was pretty clear when calling schools 'an artificial and inefficient learning environment' with 'no intrinsic value' meant to mold children in a socially more desirable form. These criticisms were also frequently repeated by OLPC who could also publish about how boring, stifling, and unfulfilling education could be:

These narratives resonated in the technology community as well as across American culture more broadly, where it is common, and even encouraged, to disparage public education and recount tales of terrible teachers (while excellent ones are often forgotten, and the role of school as a social leveler or cultural enricher are similarly unmentioned). In this way, the anti-charisma of school has become a common cultural trope [...] For OLPC [...] it aligned the project with this broader backlash against public school [and] it provided a rhetorical foil to ideologies of childhood – an opportunity to reinforce the importance of individualism, (technically-inclined) play, and rebellion important to the idea of childhood OLPC relies on.

Finally, computers have their own charisma. As a sort of contradictory points, they are seen as the universal machine, one that can help with self-governance, invert social institutions (the people good at computers would now be on top of the pyramid, however), ending geographic inequity, even "resetting" history; in practice however computers mostly entrenched existing power structures. The wide web had appearances of a wild west, touching libertarian sensibilities while in fact relying on large amounts of infrastructure. In the case of OLPC, the author states that "imbued with this infinite potential, laptops could take priority over teachers, healthcare, even food and water."

At the junction of all three elements, we find narratives of self-taught hackers and developers, which many of OLPC actors self-identified with. The author adds:

But as I dug deeper into how this self-learning worked, I found that in all cases they benefited from many often-unacknowledged resources. This included a stable home environment that supported creative (even rebellious) play, middle-class resources and cultural expectations, and often (though not always) a father who was a computer programmer or engineer.

This sort of connection doesn't seem to have been discussed by Negroponte nor Papert, and neither does it look like they often discussed sociotechnical infrastructure required. OLPC supporters instead seemed to focus on a few engaged children as emblems of success (in which they'd recognize themselves) and downplayed reports from the field that would contradict it.

Taking a step back, Ames says the pattern repeats itself with various technologies: the steamboat, canals, bridges, dams, skyscrapers, the telegraph, electricity, the telephone, radio, cars, tv, and airplanes. Most came with promises of peace, the elimination of manual labor, of democracy, equality, and freedom:

today’s charismatic technologies are neither natural nor inevitable, but are ideologically conservative: even as they promise revolution, they repeat the charisma of past technologies and ultimately reinforce the status quo. This, in turn, allows us to better identify new charismatic technologies and to understand charisma’s consequences.

The paper then draws more in depth on the history of radio, its initial lack of regulation, who it attracted, and how it still eventually failed to deliver. The paper agues that:

we actually prevent these technologies from having their full effect as long as we remain enthralled by their charisma. It was not until they recede into the ‘mundane’ and we understand how they could fit into the messy realities of daily life, rather than making us somehow transcend it, that they have the potential to become a strong social force.

In the case of education technology, charismatic technologies have to make big promises to secure funding, which means they are setting themselves up for failure and short lives. Some technologies like chalkboards, cheap paper, projectors have had lasting effects on school whereas charismatic technologies often did not.

Lack of understanding of the day-to-day social, cultural, and organizational roles of people involved in education led to overpromising:

When the messy, expensive, time-consuming realities of using technology in the classroom inevitably clashed with hyperbolic promises, disillusioned innovators, along with the media and the general public, would often blame schools and especially teachers for not solving problems with technological adoption that were, in reality, beyond their reach.

Change that is often piecemeal and inadequate but applied over a long time with continuous local adaptation is more effective, as it preserves what is valuable and sheds what isn't.

The author concludes:

as long as we are enthralled by charisma we might actually prevent these technologies from becoming part of the messy reality of our lives, rather than helping us transcend it. We must remember that charisma is ultimately a conservative social force. Even when charismatic technologies promise to quickly and painlessly transform our lives for the better, they appeal precisely because they echo existing stereotypes, confirm the value of existing power relations, and reinforce existing ideologies. Meanwhile, they may divert attention and resources from more complicated, expensive, or politically charged reforms that do not promise a quick fix and are thus less ‘charismatic.’

She adds that the point is not to prove charisma wrong; it can play a useful role of smoothing out contradictions and inefficiencies. The key point is to get a better understanding of when charisma is at play, to understand if technology is actually serving its purposes.
