If you want to try your hand at violating Bell inequalities, there are widgets in [1] that allow you to input strategies (as javascript) for Alice and Bob. It continuously performs Monte Carlo sampling of the strategies and presents their success rate.
There's a classical-only widget, that goes through quite some contortions behind the scenes to prevent cheating via writing to global variables, and a quantum-allowed widget where that kind of cheating is possible due to the underlying implementation cheating in precisely that using-globals way in order to correctly simulate the quantum mechanics.
Anyways, I've had a few people tell me playing around with the widgets helped them understand the inequality.
