I posted a little pendulum demo yesterday, now kind of made it into a tiny game by making some objectives and restrictions or something. Sadly only spending ~5 hrs/day on this, hopefully I'll finish with something playable (e.g. there is no win detection atm yet)

Also due to the non-deterministic nature of the system (carefully put in place in the code) you can just hit retry until you win :D

Bonus points (when there are points) for hitting the same objective multiple times, I managed to get the middle one 4 times once.
