Fortunately I had just recently seen a movie that enlightened me about urban art and artists. I was introduced to the likes of Banksy and Invader. So a few weeks later when I ran across Invader's tile calling card while meandering the Gothic quarter in Barcelona, I was extremely excited. As I was chittering and snapping a photo, a girl walking by asked me if I knew who Invader was. "Of course!" I said, feeling smug as other tourists passed around us unfazed by the space invader. Even though I'd just spent an entire Sunday afternoon cataloging tons of street art in the quarter, I was most excited to see the Barri Gotic had been Invaded.
