In terms of controls, a very nice and simple twistable one is the one on
the controller unit on my 3D printer:

With just 3 gestures (turn clockwise, anticlockwise, push) and a small
LCD it can completely control the printer including starting a print,
adjusting the target temp of the nozzle, etc.

I love rotary encoders because they are very intuitive to use, they
allow you to adjust settings quickly (it's quicker to turn the knob a
few clicks than press repeatedly on a button) and they don't cost a
fortune:
