Droplets 2

A demonstration of some of the improvements I've made in my project since Droplets. This version features:
- Friction: smaller drops move more slowly, and it's possible for drops to not move at all.
- Variable hydrophobicity: the green region in the center represents a hydrophobic coating, which has a number of interesting properties resulting from the fact that it repels water.
- Snazzy new high-resolution graphics.
- An algorithm (not depicted) to classify and graphically isolate each discrete drop in the simulation.

EDIT: Here is a demo of the drop isolation algorithm.
