Project 2. 3rd post

Ok Ive settled on my final idea and started coding it. sort of. My Idea is similar to the one before except all the shapes are circles. When the mouse is pressed it will create a circle that bounces off the sides of the screen, when it hits the side it will create a tone from  scale, I have chosen the E major for conveniences sake. Depending on where the mouse is the circle will be a certain colour and produce a certain tone when it hits the side. Heres what Ive coded so far http://www.openprocessing.org/visuals/?visualID=27146. As it is they dont do anything and they are pretty plain. and theres no sound. What im going to investigate first is moving the circles.
