Sort of a Fractal, gothic, thing... I dunno, I had a picture in my head and went with it.
The second photo used is from a photo I took here in my hometown. It is a photo of a dome that I created a pseudo-HDR using qtpfsgui and ev-altered raws. The source photo is actually ONE of the photos that was rendered through it. Whatever pl was short for... can't remember - don't think I liked the result as much as the others though, as I recall.
