Bending Light - a new PhET sim

The good people at PhET have launched a new physics simulation into the world.

Bending Light. It's a robust refraction sim with many tools and options. PhET says:

Explore bending of light between two mediums with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

PhET sims now have an "embed" feature (very groovy). So click on the screen shot below to launch the sim, itself!
