I was recently approached by a mathematician who is also following the 'ice-in' on Shawn and Kiwis camera on the East end. He also passed along a url:

http://lakeice.squarespace.com/ice-growth/

I followed it right up to the pretty picture and the details section...
Actually the site is full of interesting info about Lake Ice, and not the kind that tinkles in your beverage glass.
