If you haven't seen it yet, here is Marco Brambilla's Civilization, a massive collage of found footage arranged as an ascending tableaux of Hell, Purgatory, Earth, and Heaven. Every little nook and cranny is crammed with tiny snippets of video imagery from innumerable sources, both recognizable and obscure. It's pretty intense.
Check out Brambilla's website for more of his works. It seems to be a little hit and miss, (An exploration of cyber-cafe Counterstrike players? Yawn.) but if you are at all interested in video installation artworks, check out Cyclorama and Sequel.
Also, why do fine artists always insist on having left-to-right scrolling websites?
I'm addicted to using parentheses, (Ooooh, that's the stuff) I watch a lot of very strange and/or obscure movies, I love videogames, I make promotional videos for sporting goods, I have a totally sweet dog who is lazier than I am, and I will most likely never finish the Sci-Fi novel I'm writing.
