So I was getting burned out trying to get Ackermann steering geometry into my VW Thing in a sensible way and wanted to do something quick and fun and maybe explore / abuse / stress-test the point-cloud contact model.
So I made a Zorb:

It's just a transparent sphere (hand-crafted mesh again, of course). But all 290 vertices are also touchdown points, with stiffness and damping set to approximate a nicely bouncy ball. The weight, size, drag characteristics are all appropriate for a real Zorb.
And then I set up a scenario where I dropped it over the Alps with the wind turned on. Falling at terminal velocity of 20 m/s, no steering, just going wherever the wind and bounces take me...

This should be interesting...
