The Wooden Virus IQ puzzle looks incredibly difficult to solve. The game includes 12 wooden rods and 12 wooden tube0like pieces which you have to construct together around a red nucleus (red ball). The rods go in and out of various tubes with holes positioned strategically so that one rod can only have one corresponding place in the entire puzzle.

There’s no doubt that this puzzle is challenging, and I sort of want one just to fool around with. This website sells it for $6.50. [via]
