Foam Guy was one of those projects where you have the materials sitting around, so you do something, and it actually turns out OK. The sculpture is a rough human shape with a red marble for a heart, and a blue marble for single, all seeing eye.
I started with a block of gray foam rubber that had been packing material, and just carved out this guy using a razor knife. The cuts for the eye and heart were a little tricky, but since the whole thing is rather stylized it didn't matter too much. The marbles are just held in place by friction.
