This super-fun octahedron-tetrahedron crystal "ThinkerToy" swing spins 6 swings high and fast! Always the highlight of the party for kids and adults!
Suspended from guy cables at the top, rotating on bearings bottom and top, six swings spin out in a breath-taking ride, powered by pushers at the base.

The 8-vertex shape of this swing is the simplest definition of the (fcc) crystal structure of gold. Ten foot aluminum struts screw into 12-nut hubs ~ easily assembled and disassembled.
Even one pusher can get the swings spinning fast ~ the more pushers the higher the ride! Lower tetrahedron is a two-frequency revolving climber. This swing has been in continual use at various locations for 37 years!
