the illusion is very delicate. press space to spawn a new point. move it around by clicking and dragging. hold the 2 key and click on a point to move it backwards, then when you're ready, press 1 to activate the simulation. you can only move forward and back.
99% of this came from my own brain so even though we cracked 3d years ago, I'm struggling with the math of rotating the object, and moving left and right.
