I had an interesting discussion about how skateboard trucks worked. We wanted to understand how changing hanger angles affected how the board turned. I ended up building a visual simulator.

Note, to operate the board, set hanger axis angle and rake, then adjust board tilt dynamically. Note at high rake angles, things get jumpy. Need a bit more coding to ensure the dynamics are smooth. Any coding volunteers? Contact us!
