I had some time this morning to try a project - find interesting textures around my house and make abstract images from them. Easy enough, and I came in with little vision for what the final product would look like except that I wanted them to be unrecognizable from their original form.
If this works well, you won't have any idea what these things are, and I'll bet you a doughnut you can't guess but 1 or 2. 
The fun part was that as I processed the photos, I found myself envisioning a lunar/Martian landscape - barren, rocky, cold, colorless...and a little weird. Maybe with an alien! Check these out and I hope you find them cool. Bonus points for guessing what they are in the comments.
Images from the Mars Rover?
