A triangle drawn with an ultraviolet laser pointer with an 8″ exposure on a tripod. It was hard to get the sides right, but I think laser pointers are a lot of fun for photos.
This was on the night of the lunar eclipse, 2010-12-21. I was getting bored waiting for the eclipse to reach totality so I did this.
