Going to the World Maker Faire isn’t all fun and games; sometimes you have to suck it up, pay $130 in cab fare, buy $7 Heinekens, and crash the super not-so-secret after party.  While the company was fantastic, one of the more exciting interactions was [Jim Rodda]’s Seej, a tower-defense-ish game constructed entirely of 3D printed weapons, flags, and blocks.

The goal of the game is simple: Each player gets a Seej engine, some blocks, a few pennies, and three flags. The first person to topple all three flags with ballistic pennies is declared the winner. The Seej engines aren’t just limited to the red and black catapults shown above; there are plans for a ballista available, and we’re sure someone will add a 3D printed trebuchet the the arsenal at some point. We’ve seen at least one example floating around the web.

In all honesty, this game is really fun and well worth the frustration experienced by a pitiable bartender who I hope was tipped well for the night.
