The seven-piece cube puzzle by Piet Hein, rendered here in wood with a lovely checkerboard pattern.

I loved fooling around with the standard blue plastic Soma cube as a kid. This wood version is a much nicer quality and much more attractive version of the same puzzle. The light and dark colored wood makes for an attractive cube design, but only a few of the many cube solutions produce exactly this pattern giving an extra challenge.

Sweet! This is exactly the same as the puzzle I picked up in Prague!

Leave it on your coffee table and it will act like a decorative cube. Watch your frustrated guests try to put it back together after their curiosity gets the best of them.

One of the little things that make me happy! (via VintageReader)
