I always thought the Amiga 64KiB demos absolutely rocked. They do. They are awesome. Especially the music (for most, anyway) like "I want to be machine" (I think that was it).
Anyway, a friend showed me "The Product" for Wintel PCs. It's 63.5KiB. And there is no way any 68k Amiga could ever come close.
http://theproduct.de/It doesn't really run on my P-II 300Mhz/TNT16MiB, but that's OK - this demo really does utilise those resources! Must eat lots of memory, takes ages to decompress..
Truly an incredible feat of assembly, mathematics and forsight... the amount of detail is incredible; it uses mathematic expressions to generate textures, camera motion, objects... damn.
This one demo for the PC is probably responsible for a lot of PC demo coders just giving up - since they have to be compared to the product!
