MouseClick

I've managed to create the 'light' using the mouse click. So when the interactor holds the mouse the 'light' continuially falls. The problem at the moment is that it doesn't refresh what you have done. So if I let go of the mouse half way through the 'light' falling it just picks up from where it left off. And also once finished it doesn't start back up again. This is something I am looking into to fix and make better. By possibly using loop()?
