Sigurdur Stefnisson took some neato photos of a volcanic eruption at the Eyjafjallajokull ice cap in Iceland in 2010. A bunch of them would make pretty great desktop images if not for the fact that none of them are available larger than 640 x 426. Alas.
Anyway I chose to post this one, titled only with the identifier shs_n3_045824, because that is totally a lightning dragon flying out to the left. Check that shit out. That is a fucking dragon.
