Simulates an elliptical orbit using parametric polar coordinates.
Up / down: adjust radius
Left / right: adjust eccentricity
Note: weird things happen when the particle goes off screen and the internal coordinates reset, but the calculated numbers should work fine.
v0.2:
fixed some math equations
- eccentricity now accurately presented (for the most part)
