Finals Concept: Double Pendulum

I’ve been very fascinated about kinetic sculptures recently. I would like to create a “painting” that is created through mechanical methods, specifically using the double pendulum, which creates beautiful, random-looking patterns.

This has been done with LEDs before:

However, with LEDs, you can’t see the full patterns unless you record or photograph it. I would like to use thermochromic paint that would capture its trajectory long enough to be visual, but will disappear over time to start again.

My two main concerns are how to blend thermochromic pigments with a medium that will allow it to go transparent and be able to spray it evenly onto acrylics, as well as how to wire the spinning arms so that the tips are heated only, but still allow it to spin without getting tangled.
