Besides exploring basic geometry, he managed to give his objects a solidity in appearance (and potentially in mechanical behaviour) that eluded me. I totally enjoy the ethereal appearance of some of my own structures, and managed to resist the call for more solid struts.

While playing with the Java tensegrity viewer by Bob Burkhardt, a pioneer of constructing tensegrity structures, I realised have easy it should be to build a 12 strut tetrahedron like Pars did. I had a small colourful tetrahedron lying around, and decided to transform it.

The proximity of the struts could easily be changed by upsizing. The corners are held together in a single spot, I'm tempted to connect the corners to the center. Well, as the first emanation with 60 cm struts already has quite a large prestress, I might delay this idea until the next build.

Using two colours for the tendons allows to show the 'centre' and 'periphery' of the x-module. Using two colours for the four struts will enhance the polarity of the struts, could be fun be find out how a chain of x-modules behaves. I did this before, very early in my tensegrity exploration, certainly worth doing again.
