The September 11 entry on Wooster is a bit of history; Wooster Collective: Our Story. The site founder explains that at the time of the attacks, he and his partner were living near the World Trade Center in the West Village.
He watched the second plane hit. He watched the towers fall. More importantly, he watched the city come together as a community.
And it was at this time, in the days immediately after September 11, that we discovered ephemeral art. Until then we had no idea what street art was. But the attacks of September 11th had made us hyper-aware of our surroundings. We began exploring Lower Manhattan like never before. We were now seeing the city in a completely different way, with new eyes and a new heart. Everything, and everyone, around us was now suddenly important. And it was in these days immediately after September 11th that we began noticing street art everywhere we went.He started photographing. Eventually he put what he found on-line. It caught on, and Wooster Collective was born. I am paraphrasing. The full post is well worth a read.
It's heartening to find another positive result of the attacks of 9/11. It shows that humans are capable of creating good from evil. You have only to keep looking, and keep your heart open.
