This sculptural assembly kit allows you to build a new form of life from humble plastic tubes—a mechanical skeleton that walks on the wind. The "Strandbeest" resembles a caterpillar made of clockworks. All it takes is a strong breeze to bring the contraption to life and it moves with an elaborate form of locomotion that has to be seen to be believed. Illustrated instructions are included with the 117-piece kit which requires no special tools to assemble. Construction time is approximately 90 minutes for ages 8 and up. Once assembled, the Strandbeest measures approximately 6"x5"x8". Designed by world-renowned artist Theo Jansen whose work has been featured in The New Yorker and on The Simpsons.
