|Base joined tetrahedral tensigrity|
It's the Illuminati tensegrity - 2 triangular and 3 square corners, the geometry strengthening diamond. Build properly, it will balance on the square corners around its girth, albeit very delicately. Suspended, it should show horizontal stability between the triangular corners.
I experimented with connecting the former corners (crossings) centrally instead of outlining triangle, squares and pentagons. I'm not too sure about the classification of tendons connecting in a hub without compression elements, but it adds functional and aesthetic qualities.
The central junction of three corner tendons can act as a mount point for anything suspended in the centre. I had a spiral made of six shorter sticks which needs a pull from either ends to maintain a 3d shape. I looped string around the centre of the outer sticks and attached the elastic string to the junction of the two triangular corners in the structure.
I did my best with a random spray job for the outer struts, balanced on one triangular corner it measures more than 2 metres. I have no idea about its durability - it uses elastic strings around its girth (which I might replace), and elastic to suspend the central spiral.
While I liked to call my sculptures 'kinetic', this one fits the description. The slightest amount of wind gets movement into it, either by rotating the centre or the entire structure. It's like a mothership of randomness, another turn will happen, unpredictably. Different perspectives provide different colour aspects, just like the rotation. Any capture seems unique, like an elephant felt up by the blind.
So I indulged in making a clip, which is still rendering in the background while I type. No idea whether I'll get in copyright trouble when uploading it, I haven't even bothered watching the final result besides bits of preview. If you're in a hurry, don't bother watching. It'll be about 15 minutes without anything spectacular happening,
The raw footage still captured lots of detail I was interested in than the GoPro footage I took before. I love the balance the single point of suspension provides, as well as the independent movement of the spiral in the centre, even though the twist pulls the entire structure together.
PS: This piece brought me most excitements from any of my creations. I had some pieces hanging, and enjoyed the movement. Many delicately balanced pieces were blown over, exploring the rotary power will bring another dimension into my work.
