I went back to Philadelphia again. It seems like like each time I got the city feels better and better. This time is was to check out Mural Arts' Open Source, a citywide public art exhibition curated by my good friend, Pedro Alonzo (pictured above with work by Swoon). We caught up with some friends as well, and had the opportunity to walk the city on a beautiful day. I've posted some of the highlights here, including some that were not officially part of Open Source.
