Site: North End electrical substation
Who: Nate Swain
From April to June, Swain planned to paint the 18 windows and two doors - a costly and time-consuming undertaking.
"Then, one day I was down on Boston Common and I saw these banners," he said. "I had this epiphany: Why don't I just do everything in Photoshop and have it printed on large-scale banners and have the banners put up on the building?"
