Calling all PPT graphics ninjas!

Help!  I've been trying to make a downward spiral in PowerPoint.  This is the best I've come up with but it is flat and the perspective is all wrong.  I need a repeating circular shape that extends downward -- to illustrate repeating downward cycles.  I've attached a ppt file with this image. 

I'd be so grateful if anyone help me make a better spiral?

You all are great!  It looks like a judicious use of gradients is key.  Graham, I've not been able to open yours yet, but will keep trying.  I'm getting an intermittent error script when I try to open the files.  And Stephanie, that is a neat trick to add the axial arrow to give the illusion of depth. I've played with that some more to add animation.  I'm liking this effect.

Just drawing something similar.
