Cool Shape Forms

Can anyone tell me a way to make cool-shaped forms? I mean circular and
other style (not only math-shapes). But not using just a TImage component. I
mean that if you click just a pixel or two out of the "form" (best from
diagonally) it mustn't count as an Click event. Or with circular components
or sth.

Any help/solution/tips would be appreciated.
