We realized in a discussion a few months ago that a lot of people younger than us have never seen art in this style - large scale black-and-white pixel art with hand dithering, meant for viewing on a low-resolution display. It could get quite elaborate. We were just able to dig up a clip art collection that was famous for being some of the best, in the day, and thought we'd share a little of it.
