I took a photo of a weird concrete war thing on Sunday, and I did stuff with it (for want of a better phrase) in Photoshop. The first pic is how it looked (albeit with some changes to brightness etc.) and the second pic is what I did with it. I think it looks like something out of a post-apocalyptic computer game.

I especially like the ones with the skies that look toxic. A bit like something from the original Doom game.
