need help/sample code for php/apache/imagemagick

hi... i'm considering creating a short test app/game to allow users to use their mouse to select items from a given image/pic. i'd like to be able to take some basic shapes, and construct an image/mosaic from them. i'd then like to be able to display the image to the user, and have the user select various shapes in the image. i'd also like to be able to determine what 'shape' the user is selecting within the image via the mouse coordinates... any ideas as to how this can be quickly developed/thrown together for testing... i kind of thought that this should be doable with php/imagemajick as an apache app.. thanks -bruce bedouglas@earthlink.net
