One day, once I've collected enough cardboard boxes, I will use my projector to make a life sized one (which means it's going to be HUGE). In the mean time I've assembled this prototype. I glued the print outs on to poster board, but I got a blister. I would suggest cereal or chip box type cardboard instead- you may just need some glue to keep it in place with thinner cardboard. Click on the images below to enlarge/ save. If I did it right the pattern should fit nicely on to two 8.5" x 11" sized paper.
