For this, the last day of the US Fiscal Year, here's a lovely time lapse video from Tadas Janušonis, a photographer in Lithuania. It's called "All is Violent, All is Bright", and features a series of interesting optical phenomena in the sky.
But my favorite is the phenomenal oncoming storm starting three minutes in.
That, or the giant spider (at 2:40) clearly bent on destroying the world. I'm partial to stuff like that.
