Design Within Reach has these really cool building blocks for you, your kid, or anyone. I bet they are really fun to play with when you’re stoned. Here’s the lowdown from there site….

“First designed as an instructional game for Swiss schoolchildren, the Cuboro Standard Building Block Set (1979) has evolved into a labyrinth designing exercise for all ages, including those old enough to run a company. Configurable in infinite combinations, the weighted marbles travel and forge their own path through underground tracks and hidden passages. The Building Block Set encourages experimentation and activates the discovery of spatial, mathematical and aesthetic problem solving. Help your child, and yourself, transition from a two-dimensional to a 3D world by constructing something highly functional that isn’t necessarily seen by the visible eye. The Cuboro Set contains 54 FSC-certified beech wood blocks and three colored marbles and can be added to with additional sets to expand the possibilities even further. Contains small parts; not recommended for young children.”
