Flutterby! : flippin’ the bird
Dan took some nice pictures while walking around San Francisco today. He snapped this picture:

which I liked, but I thought could use a bit more oomph. So, I fired up gimp, cut the bird out, and manipulated the contrast of the bird and the background separately, and came up with this.

Probably overdid the blacks and whites, but I was only really goofing around. I really like The Gimp.
