Control theory for fun can be really fun. Using control systems for solving problems you are familiar with can help develop an intuition, that you can then map to other problem domains. Years ago a peer at LucasArts taught me how to use PIDs for game cameras, and I've used them everywhere since.

Very simple rules can create lifelike emergent behavior. This is an example of 2 simple motors using PID to try to target a red dot, in 3D, with gravity on: https://www.youtube.com/watch?v=8hfKs02QHR4&list=PLpDgOnZpfh...

I can watch control systems all day.
