This is a Wheatley Personality Core puppet from Portal 2. It has light-up effects (read: a giant blue lightbulb for an eye), is programmed with ten different quotes from the game, and is controlled by putting your hand up its ass and pulling levers or whatever. I dunno, puppets creep me the f*** out. "What about marionettes?" *shivers* GOD YOU JUST HAD TO GO THERE, DIDN'T YOU?
Hit the jump for a short worthwhile video of Wheatley in action as well as a link the build blog if you're interested in making something similar.

Thanks to stu and Harry, who don't put their hands up anything's ass except turkeys.
