Robot Halloween Costume

The humans are dead!
I originally got the idea for this costume from the Flight of the Conchords song "Robots".

It was quite simple to make. I started by asking around a few stores for boxes until I found ones the right size (small one for the head, large one for the body). I also found a few toilet paper rolls to use for the "antennas" on the sides. Then all you need is foil, black card and green paint!
