A nice perfect storm happened that led me to transition (just a tiny bit) to working with squishy, rather unpredictable surfaces in opposition to what I normally work with (analytically predetermined shapes on hard materials).

A couple of weeks ago, just after the AAG workshop, Yiwei Zhang, from Tachi Lab visited Boston, and we hung out one evening at the CBA doing some inflatables.

In a parallel way, Duks has been talking to me about doing a soft folding inflatable project, and then, on top of that, as I am TAing HTMAA, I was teaching this week (wildcard week!) inflatables using ultrasonic welding!

All this converged into me having the interest, curiosity, time, and resources to do this.

So find here some bi-stable tripods that can reassemble into the modular polyhedra you often see here.

Tripods as a tetrahedron, and its dual is another tetrahedron.


I did this using the Zund Digital Cutter that I attached an ultrasonic welder (inspired by the workflow of Hye Jun Youn), and it is working like a charm.
