Lake Superior ice stacking

I've never seen this natural phenomenon before. It looks pretty cool. It's called ice stacking and it happens when wind pushes the top layer of ice on top of unfrozen water. This particular video shows it happening on Lake Superior in Duluth, MN. Remind you of broken glass? Hopefully not as dangerous as a pile of glass.
