Patterns everywhere

I took a particular liking to doors in Prague, as you can probably tell by all the doorhandle posts. The doors themselves are frequently very interesting, as well. Here's a carved wooden door with strong geometric patterns. As you can probably tell, I've boosted the heck out of the image's contrast to exaggerate the patterns.

By the way, without my even noticing it, chromalark has passed the 200-image mark.
