Originally from New York, Ripo now lives in Spain, his typeface is created by using white enamel paint on mirrors, then photographing the resulting refections. He says, "Graffiti usually fills in the negative or forgotten spaces of cities - ignored parts of signs, doors, walls.... I played off this concept by painting in the negative spaces of the letters and letting the city fill in the rest". Visit his website to see more.
