Cool negative/positive graffiti effect on San Francisco’s Broadway Tunnel. “Kitchen porter” runs with the idea of cleaning grime from a kitchen. The graffiti is supposed to be of indigenous plants that lived where the tunnel is now and, of course, has an environmental message. Of course. Cool effort, though.

I was surprised to learn that Golden Gate Park was once just dunes of sand and known as “The Great Sand Bank.” There is something to be said about terraforming, introducing non-indigenous plants and biodiversity.

Ssssout.
