If you know any puzzle lovers that might need a Christmas or whatnot gift, just found this. Really cool wooden puzzles that have science based themes, one of them becomes a playable chess board, the shapes aren't "puzzle" shapes, very cool stuff.
The lamp might be a tad out of most of our budgets, but the effect should be admired.
