Balls Everywhere!!

LOL so I made multiple bouncy balls on the screen, all with seperate colours, directions and speeds. But I'm pretty sure I did it in a horrendously roundabout way... I did seperate random variables for each aspect of each ball :P
Anyway, here's what it looks like now...

Now I need to integrate the two aspects I have right now into one interactive code. And then continue to develop what happens during the chain reaction event.
