Pong Assist Graphic Representation

So, it occurred to me, after watching the velocity-tracking program I wrote spit out endless values at me, that it might be useful to have a computer animation of the ball, Pong Assist paddle, and starting and ending trajectories, so that, in the future, I can differentiate between hardware problems and programming problems. As a result, I've begun work on a Processing program that will produce a visual of the intended interaction of paddle and ball. Below, I've posted a drawing of what I want the representation to resemble eventually and a video of what I have so far. Needless to say, there's a long way to go, but I'm pretty happy with how things look so far.

Intended Visual Representation Layout:

Progress So Far (loooong way to go)
