Steel, glow glass, rare-earth magnets, 3 x 3 x 3"

Four parts snap together to make this sculpture. The magnets holding it together are just right, so you can handle the whole with confidence, or pull it apart to explore the interior. Together or as pieces, it's irresistibly tactile.

The assembly isn't difficult enough to be a puzzle, but I will say that there are two solutions, and it took me some time to notice the second.
