Tokyo Plastic v2 - amazing! www.tokyoplastic.com
First the linky:
http://www.tokyoplastic.com/
( click the "Enter Tokyo Plastic v2" link and let it open its new window... you'll probably be there for a while )
I didn't exactly find this myself, rather I followed a link from a link from Zeldman.
But anyway....
As an interactive site it's only pretty good, but as animation it's just amazing. My brain nearly asploded trying to imagine doing all that in Flash.
Anyway check it out. Don't bother going to their print store though, the prints are all sold out already.
