San Francisco’s Mosaic Staircase. Hidden art gem in San Francisco; head to and Moraga to discover The Avenue Tiled Steps. Not only will you be able to see some amazing views of the city, you'll get to appreciate a beautiful mosaic running up 163 steps.
I’m not a big “skull art” fan, but I dig this photograph of a wee butterfly (or is that a moth?) landing inside the eye socket of a human skull. The image, by photographer Marko Popadic, is called Oko (Polish for “eye”).
