Heart-to-Heart was designed with the Gearify v2 software by Michael Valle (
https://www.gearifysoftware.com/). I was invited as beta tester of new version 2, which suppors involute gears. I started with a heart shape, and let gearify calculate its companion. I took the average of the two shape, and repeated the process a few times. The results is two nearly-mirror-identical heart shapes that roll around each other. It is a fidget toy. Its purpose to roll it endlessly and to stay mesmerized.
