Ellipse Drawer

Still not working exactly like I would prefer. The sideBar seems to be interfering with the execution of the code.


I modeled this after a Max/MSP/Jitter patch that performed more elegant options and drawing. That program took about 2-3 hours... this on the other hand took much, much longer. I did learn how to utilize classes and subclasses, but the program did not turn out how I hoped it would.

I made my usual mistake and did a top down design... this leaves the drawing area separated from the rollover menu, which essentially defeats the purpose of having a rollover menu. Regardless, it is fun to be able to manipulate the auto-drawer despite the fact that it pauses.

I did not have time to add an e

Buttons now perform the divide and multiply actions that the bouncing ball performed in the previous project.
