Tried to recreate natural looking/feeling bubbles...

Link to Sim

I don't know, these bubbles just make me feel good. Relaxed..

I imagine someone to be blowing these bubbles from the bottom left of the screen. I tried to add some sort of rightward push, gravity, buoyancy(?) and other forces to these bubbles so that they would float around in a realistic sense. Clicking on the bubbles also makes them pop.
