Norway's weird spiral sky lights

This footage was taken early this morning in Norway, and nobody seems to know what it is. The crackpots are out there talking about UFOs, 2012 and the Large Hadron Collider. But nobody seems to know what is it.

The Russians are denying that it was the result of a rocket test.

It really doesn't look like the aurora borealis.

Any theories from any of you?

Personally, I'm hoping it's a test of some tech based on Tesla's work. Death ray, anyone?

Or maybe a wormhole opened up!

UPDATE: Occam's Razor is a pretty useful thing. It's also often disappointing. The most likely explanation for the spirals in the sky was a failed Russian missile test. Now New Scientist is reporting that, despite Russia's earlier denials, a failed missile test is exactly what cause the strange sight.
