Playing with Processing

I was playing with processing yesterday, always want to learn how to do it, but never get my self together to try it during my free time.

I made this bouncing bubble thing base off a example on the processing's website.
the bubbles fall toward the bottom with gravity, and when hitting the edge, fiction slow them down.
when hit each other they fly apart and heat up a little bit.
when mouse click, it attract the bubbles and heat them up crazy.
once let go they slowly cool down.

the end of the story...good night~ :D
