how about an empty hobby-box challenge?
idea: create the most interesting, funny or otherwise amusing structure or costume entirely from empty hobby boxes.
a Pack-Man contest -
you could sell a lot of say 20-40 single packs along with a blowout t-shirt (the packs can be random stuff that normally would not move) and have the contestants fasten them to the blowout shirt, and have a vote for the best display/showmanship/design. winner gets to be the "mascot" for blowout cards, affectionately known as Pack-Man.
the fact that we exist, in a universe of sheer randomness, is scientific proof that there are aliens.
we are the aliens.
i can say that with 100% accuracy.
