Near Lake Mills, Wis., out on frozen Rock Lake, archeologists discovered an ancient ice carving that they theorize was built as a temple to Wisconsin’s harsh spirit of winter. Not really. It was actually built because five guys got bored and decided to just make it, man. Eli Wedel Photo & Design has more pictures and information on the carving, which lasted for several days before being taken down for safety concerns (when they start to melt, 200 pound slabs of ice can get a little slippy-slidey). At any rate, it's a great example of boredom producing something, ahem, cool.
