A friend of mine linked me this awesome pic, a "Where's Waldo" with fictional robots.
There are robots from all genres and media in here. I've spotted one from an obscure short indie film and got a little hit of the joy that hipsters crave, and found an easter egg for the Asimov readers.
Still I can't identify all of the robots. To do that will take knowledge of everything from classic sci-fi to current kids' cartoons. Fun for the whole geek family!
