In a neighborhood where nearly every tag is gang-related or the work of one particular ubiquitous tool who has written the same three initials on just about every bare surface available, it's refreshing to see some genuinely clever, whimsical street art. In between white road buttons at Kiest Boulevard and Polk Street, and on another street or two we've noticed, someone has stenciled Pac-man, Ms. Pac-man and colorful ghosts from the arcade game. They're just the right size to be in the right proportion to make the road buttons look like power pellets. They're starting to fade, though, so hopefully the artist will come back and insert another quarter with his or her spray paint.
