Frozen Water "Sine Wave"

Some more video awesomeness.

I'm not sure I would call that a "sine" wave as Boing Boing did... but all the same some pretty cool visuals and some great potential links to physics and math. I'm teaching trig to my SL kids at the moment, might make for an interesting diversion. There is no place in the SL curriculum that hints that parameters such as amplitude and period can be functions rather than just constants...
