Dad’s need new toys too. Following the tradition of Father’s Day in our house, I not only get the requisite hand-made goodies from my kids, but I usually get something to play with too. This year I got a Hoberman Sphere. If you’ve never played with one of these things, track one down. They are an immensely fascinating combination of art, mechanics, and symmetrical geometry. Basically the sphere is a series of interconnected plastic struts that expand from a small 9 inch diameter ball out to a 30 inch sphere reminiscent of a geodesic structure. And now, Chuck Hoberman has come out with a the Expandagon Construction System so budding kinetic architects like me can create our own mechanical art. Now, if I can just figure out a way to meld the Expandagons with the Lego Mindstorms.
