Heh. I wrote a JavaScript DHTML demo in 1999 that I locked to a browser window sized 640x480px because otherwise it made PCs grind to a halt and crashed Macs. Nowadays it runs on my phone just fine... Link for anyone who's interested: http://www.gilesthomas.com/old-javascript/stars/index.html
Ironically, this is what I put together in 2009 (ten years after the DHTML demo) and it also crashed browsers then, and it also runs on my phone now: http://learningwebgl.com/blog/?page_id=1217
