Rotate controls in a circle

I want to be able to rotate controls on a form in a circular shape.
My lack of geometry kills leaves me scratching my head for this one.

I attached an unsuccessful example that rotates the controls in a rhombus.
For some reason the "path" of the controls is expanding, i.e. they move further away from the center.


Please explain how this can be achieved.
Thanks.

Something like this? The top left of the image is the point that is describing the circle, you might want to add offsets to x and y to make the centre of the image trace the circle.

The code works perfect!
