This city's big on public art, but how many times have you wanted to know who's behind what you're seeing? ArtAround, a public art technology platform first launched in Washington, D.C., aims to help answer those questions. The app's founders are now working with the SF Arts Commission to launch its mapping service in San Francisco. They already have 800 pieces of art owned by the city mapped out with photos, and they're working on expanding their service to include all the other great street art like murals and graffiti that aren't owned by the city. So, you can finally figure out who made your favorite Mission mural that you walk past everyday.
