This is, as close as we can get in 2013 anyway, a real version of RoboCop's famous ED-209. It's reportedly an actual Hollywood prop, built for RoboCop 2, and stands ten-feet tall.
It won't move or shoot executives in the face, but then, it's "only" $25,000, available via an eBay auction. A real executive face-shooter would surely cost a lot more than that.
I wonder if the "complete transaction" screen gives you only ten seconds to comply...
