pattern and color; details

I was messing around with cropping and color saturation in Picasa. I'm still not sure what I think about street art overall in terms of its legality (I believe the artwork in all these photos was sanctioned by the property owner), but the amount of work that went into all of this is just phenomenal.

And when you looke at it closely, the colors and patterns are amazing! (be sure to click on the photos to see them larger.)
