They seem to be getting sketchier and sketchier. I personally wish they wouldnt add so many that are greyscale instead of thick line art (which in my opinion is easier to see).
Okay I don't mean to bump this to hard but it was annoying me beyond heck. #14 or the 2nd one right into the 3 row down looks like the klingon (sp) empire logo from Star Trek except a little rounded on the sides.
