The street art of Joshua Callaghan masks unsightly utility boxes by covering them with digital prints of what you would see if the utility boxes weren't there. We're not sure that last sentence made sense, but these galleries of his work should help clarify. His stuff is sort of like a digital trompe-l'œil. We're surprised we hadn't heard about this guy long ago, given that he's right in our back yard.More from Joshua at www.joshuacallaghan.com
