ZOOB is is an award winning building system that can articulate and move. The design is based on a living & natural system; the 5 nucleic acids that are the building blocks of life. "Its mobility mirrors the natural movement of people, animals, and machines. ZOOB pieces snap, click, and pop together to form joints that rotate, limbs that extend,axles that spin.
