I overlooked something simple about how animate is supposed to work.
Replace the "bar = ... " to this:
bar = animate([line([((R-r)*cos(i), (R-r)*sin(i)),
(g(i), f(i))
],
thickness = thicknessOfBar,
rgbcolor=colorOfBar)
for i in xsrange(0, rotations*2*pi + step,
step)],
xmin=-sizeOfGraph, ymin=-sizeOfGraph,
xmax= sizeOfGraph, ymax= sizeOfGraph,
figsize=[figuresize,figuresize])
Works for me (note that the Eye of GNOME doesn't show the proper gif
animation (at least in Ubuntu)).
