Maybe a mural, part one

Depending on how you define "mural," these mosaic panels on an overpass might or might not qualify. (Here's what dictionary.com says.) I say that if it's creative and it's on a wall (and it's not just a bunch of taggers' initials), a lot of art lovers will probably enjoy seeing it.

Whatever these are, they're on Speedway between Pantano and Camino Seco.
