I don't have it with me, but I can hopefully describe enough of it to you guys to help me figure out what it was called. I tried Googling, but it hasn't helped. Clear or Blue spheres with octagon connections, all equally 90 degrees a part from each other. As in, top, bottom, and 4 around the radius. There were axles you could put between two of the connections, or even 4 way, and 6 way axles. All of them had gears on the ends. There were blue and red cables to connect to motors, and even a robot module that did sounds, lights, and motors. Wheels, propellers, more could be attached to the gears. There was one set (previously mentioned) that was a robot, there were boats and submarines, but also just expansion packs for building. Please help me find out the name of these! I used to love these things and I really want my son to be able to check these out.
