This should be interesting to check out.
http://www.theprodukkt.com/.kkrieger is a quite nice looking short fps. Very nice indeed... for a game that's less then 100kb! That's not a typo. 100kb. Unbelievable.
.debris is very very beatiful demo video by any standard. Yet it's file size is just 177kb.
Reminds me of conversations about filesizes in
Ai ga Tomaranai and
Buttobi CPU. It's not the filesizes but how it's used!
