URGENT: Putting a 2d circle into my animation

[willg...@hotmail.co.uk]

Please help, my coursework deadline is tomorrow.
I'm doing a piece on circular motion, I have a simple animation of a point moving in a circle, and a static circle I want the point to move around on but I want the circle to sit behind the animation so that it looks like the point is moving around the circle. Probably really simple but I'm struggling...
this is the code i have--

a = animate([point2d(((5*sin(i)),(5*cos(i))),rgbcolor=hue(1), size=30)for i in srange(0,2*pi,0.1)],xmin=-5,ymin=-5,xmax=5,ymax=5,figsize=[4,4])
b = circle((0,0),5)

a.show()
b.show()

How about this: define the circle "b" first, then animate "b+point2d(...)" instead of just "point2d(...)":

b = circle((0,0),5)
a = animate([b+point2d(((5*sin(i)),(5*cos(i))),rgbcolor=hue(1), size=30)for i in srange(0,2*pi,0.1)],xmin=-5,ymin=-5,xmax=5,ymax=5,figsize=[4,4])
a.show()

Does the zorder option do what you want?

No, because they are making two different plots with the two different
show() calls.

John's solution should work, though.
