Here's a quickie stack I wrote after reading Richmond's email, which creates a set of points in an oval and then sends a planet around. The oval can be set to width (k), height (h), and angle (theta). Written in 5.5.5. Embedded in it is a stack script which contains the angled ellipse calculation x = h + (a*cos(t) * cos(theta)) - (b*sin(t) * sin(theta)), y = k + (a*cos(t) * sin(theta)) + (b*sin(t) * cos(theta)). Play.
