This motion capture/computer graphics video from from Method Studios showcased by Cory Doctorow ought to be used to study the uncanny valley hypothesis. It’s said that as robots start seeming human, but not quite, that will weird people out more than would robots that are indubitably and clearly non-human. Well, what about when humans start seeming like something else?
I think the string people at 0:22 and 1:43 and 2:10 are pretty creepy. YMMV.
