radial shape tween

I am trying to use a mask to reveal an image with a clock-like secondhand radial sweep (typical transition since the beginning of time)and am going crazy with the shape change and using shape hints. I don't want to use pieces of a circle that go together in increments which would give a jerky motion. I want a smooth sweep.

Surely somebody has done this before.

thanks,
Dennis

Hi...
You can use this if you like......no action script ...just keyframes;)

Thank you very much.

I have the exact same problem its tearing me apart :(

@daftnot2: please provide your FLA file and what you want to mask, and I'll write a script accordingly :)
