Weird glitch while I was attempting to draw bezier curves that go off the screen. Not want I wanted it to do, but it looks cool. Click and drag the curves to change their shape. Press the 1, 2, 3, 4, or 5 keys to change the smoothness of the curve.
The glitch was due to a mathematical oversight, where I attempted to draw lines that did not appear on the screen. Any segments on the curve that fell off the screen seem to be drawn as if they were extended infinitely.
