What is the name of this flash game I played but cannot remember?

The game was a flash game online. It was very simple. When you start, there are circles of pastel colors floating around within a box and bouncing off the walls slowly. The music was very calming. You are given a goal that consists of a number. You click the mouse to create a new circle, and this one grows slowly to start touching other circles. Once a circle is touched it grows also to touch other ones. The goal is to touch as many circles as possible. The circles only grow a certain size and then disappear. Any help please?
