Swiss artist Corinne Vionnet creates art for her series "Photo Opportunities" by overlaying hundreds of tourist photos (she finds them online) on top of one another. What she ends are these beautiful, shimmering things—Boing Boing calls them "metaportraits"—that are as recognizable as they are eerie. They look almost like oil paintings, don't they? Or photographs of ghosts? There is something nice about creating something so otherworldly out of such photographic banality.
