Today, we're kicking off a Seastead Design Contest with a $1,000 Grand Prize and lots of other great awards. To win, use 3-D modeling software to build the best-looking and most creative seastead you can. We supply you with a 3-D model of a bare ClubStead platform -- what you create on top of that platform is up to you.

Google's 3D Warehouse for SketchUp models has a weekly challenge. Last week's was to model a floating home.
