Produce a "penny arcade" style entertainment machine that will entertain and engage a customer/viewer/operator. Your machine may achieve this goal through any number of strategies, which might include ideas such as having an interactive gaming component, performing a set of interesting motions set to music, being a piece of interactive modern art, or implementing any other creative idea. If you've never been in an old-school penny arcade, look it up on the internet - these were pre-videogame arcades with things like skeeball, shooting galleries, memory and strength games, horseraces, pinball, etc.
