An animation of a parametric curve. The curve is defined by
x = 5cos(t) - 5cos(80t)sin(t) y = 2sin(t) - 2sin(80t) t ∈ [0,2pi]
I was cleaning my apartment and found the equations in some old notes. The frames (i.e., 2*pi*100 + 1 static images) were generated using AutoCAD 2009 and an AutoLISP program that I wrote last year. Feel free to let me know where you may have seen it before… .
