chinese are known for spamming everyone else however do they have any hardware/software projects that stand out, Talking here about Home brewed stuff not an Apple franchises and stuff (they do have some nice Iphone mods but that's another discussion)

Might you be relating amount of spam to innovation because U.S. is the spam king by a long shot?

I remember quite a few presenters with advanced subjects from Chinese institutions from last year's Siggraph. Otherwise, these are always entertaining.
