Construction set:Bizzy Bitz

The Bizzy Bitz construction set works on a simple system of connecting building pieces via a ball at the end of one tile that fits in the socket at the end of another. The ball-and-socket connections can be manipulated to form three-dimensional stuctures. The tiles come in several geometric shapes--square, triangle, circle--and the inclusion of rods, wheels, base plates, arches, and window tiles increases versatility. The manufacturer of Bizzy Bit--identified on the company website as a British husband-and-wife team and their creative children--offers several levels of constructive play, ranging from simple two-dimensional animals to complicated three-dimensional planes and trains. The sets come in several sizes: 70-piece sets up to 500-piece sets. The sets are suitable for children from age 3 to age 12.
