how are your going to create these odd shaped objects. ?

You would have to use the the form line method to draw these objects pixel by pixel. Once you have drawn the objects on the form, in the mouse down event of the form use the point method to find out what the colour(RGB) of the pixel that is clicked on. EG. if thisform.point(nXCoord, nYCoord) = 0 then the point clicked on will be black etc. so using the pixel colour you could find out on which shape he clicked on. IE. assuming each shape is a different colour. Then you could change colour or do what or do what ever you want.

hope I was helpful.all the best.
