This swing is the hit of any party!  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 crystal structure of gold. Ten foot aluminum struts screw into hubs ~ easily assembled and disassembled.

This version of the crystal swing was built in Auroville, South India. With 6 more tetrahedra than the one pictured to the right, an 8-pointed star, a “Merkabah” stellated octahedron, a dual tetrahedron, (as in drawing on right below) is created.  This shape is even more elegant and fun.  40 kids were on the swings and perched inside at once!

We’ve had lots of “Swing Parties”. The Summer Solstice 0f ‘96 was a great event, with Live Music (master drummer Saeed Abass from Africa, Wade Wilcox on percussion and Ron Rossell on bass guitar)  Timothy Hull took the picture above and a video that captures the feel of the swing & music.  He wrote poetic verse describing the event on his website....go to his subpage, “Port Mór to Aberdeen (a sometimes journal)”

poles screw into 12-nut clusters with rhombic dodecahedron facets, creating tetrahedron- octahedron grid of Face-centered cubic closs-packed crystal matrix.

Like a Tinkertoy set, this geometry can build an infinite variety of structures, such as this cubeoctahedron support for 6 minimal surface hyparbolic paraboloids, for playgrounds or modular tents.
