More progress now. On this version you can click a location and the place you click becomes the location of the spot. Now that I have this functionality it should be fairly easy to get some more dynamic information passed to my code. I think a little tidying up is needed and I need to clean up the maths so that I can use real location figures. That will be one of many steps involved in furthering this project! I need to come up with a new name aswell… any ideas??
