Noticed during holiday shopping research:

Wind Walker

Mini Strandbeest

The 8-inch model is as complex as its forebear, with 120 parts that snap together to form 12 jointed legs, a spinelike crankshaft, and a wind turbine. Ours took about 90 minutes to assemble and walked across most flat surfaces, even packed beach sand and slight inclines. The ingenious movement is hypnotic, but unlike some of the full-size beasts, which use a system of pumps and soda bottles to store energy, the Mini stops when the wind does.
