Moving Target Aiming

WebGL build of https://github.com/jhocking/MovingTargetAiming

In the interactive demo, the cannon constantly aims correctly to hit the missiles raining down. Tap the screen (or press any key) to fire a shot and watch it hit the missile.

Here's a QA page where I discuss the algorithm (plus link to the original Flash demo):

A commenter there pointed out a big advantage of my approach (versus how other people were doing it): even if there is no exact solution, the shooter will still fire roughly at the target.
