Rock Paper Robot describes its Float table as "sturdy, yet capricious"; we'd also add "potentially dangerous to your credit cards and hard-drives" to that description. The side-table is a matrix of 64 wooden cubes, using magnetism to float away from each other and a lashing of steel cable to keep the whole thing from falling apart.

The end result is an eye-catching piece of furniture which flexes when you touch it, then bounces back magically into place. Rock Paper Robot will happily make you one in any dimensions you like, with pricing kicking off at $2,000, though the standard size uses 4.5-inch cubes.
The company specialises in what it calls "kinetic furniture", but also makes lighting and other accessories.
