		// the other. This needs a pretty custom animation.

		// progress. This animator is responsible for both the translation of the bouncer,
		// and the current fade. It will fade the bouncer out while also moving it along the
		// 120dp path. Once the bouncer is fully faded out though, it will "snap" the
		// bouncer closer to its destination, then fade it back in again. The effect is that
		// the bouncer will move from 0 -> X while fading out, then
		// (destination - X) -> destination while fading back in again.
