Halloween is coming up and you need a costume, but who wants to spend the money? No one! Just follow these instructions from a resourceful Transformers fan and make an Optimus Prime suit out of cereal boxes and cardboard instead.
It cost him 20 bucks to get all the cardboard and spray paint he needed and about 5 days to cut and piece them together. It's a pretty dedicated process and the video moves pretty quickly but if you're a big fan of building things with your own hands, Optimus Prime isn't a bad project to undertake. [Instructables]
