[RESOLVED] Round Object (not shape)

So, my next challenge game is called HardBall. I want an 'object' that looks like a ball (currently simply using a shape control). BUT, as shapes are layered below most other
controls, I would like a round (circular object) that when moves around on the screen passes 'over' other controls.

Any suggestions on how to start? Maybe a circular form???? at a loss here.
