This is what I created:
It is a photo of my driveway that was partially covered in ice the other day. Here is the original shot:
I thought the ice and small bubble pockets would make an excellent alien landscape. The first thing I did was crop out the parts of the photo that just show the bare driveway. Then in Aperture I converted it to a sepia image. I also sharpened it a bit.
It was fun to create, hope you enjoyed taking a look.
