Ok, so a picture is 1 kiloword and a painting is art so we can easily work out how art each medium is. It's the number of words it is / 1000
Also, every frame is a painting, so we can also work out that a painting is worth looking at for, at most, 1/24 of a second.
Painting
A painting is one picture (or 3 if it's a triptych).
Duration: 1/24 seconds (or 1/8)
Rate: 24 art/second
Total Art: 1 (or 3) arts
Review: Fairly efficient but very short
Book
A book is 40,000 words.
A page is 250 words.
It takes a minute to read a page.
This is true of every book
Duration: 40,000 words / 250 words / page = 160 pages. 160 page / 1 page/minute = 160 / 1/60 pages/second = 9,600 seconds
Rate 4 pages/art / 1 page/minute = 1/4 art/minute = 1/240 art/second
Total Art: 40 arts
Review: More art than a painting but who has the time?
Movie
A movie is 90 minutes at 24 frames/second.
Duration: 60 * 90 = 5,400 seconds
Rate: 24 art/second
Total Art: 129,600 arts
Review: Much better than a book in both total art and art rate
Video Game
A good game runs at 60fps and is 40 hours long.
Duration: 40 * 60 * 60 = 144,000 seconds
Rate: 60 art/second
Interactivity Multiplier: 2x (obviously this makes it artier)
Total Art: 17,280,000
Review: Best by every metric
Conclusion
Games are 100x more art than the nearest equivalent so I think Roger Ebert should be forced to come back to life to apologize
