Artist Thomas Leveritt recently setup a special UV motion camera in Brooklyn's Prospect Park with the intent of filming random passersby. Ultraviolet rays have the ability to expose not-yet-visible changes to human skin, namely freckles, that turn even the most unblemished faces into dark explosions of dots. Leveritt installed a monitor above the camera so people could instantly see the results, and then to heighten the effect, supplied them sunscreen in a vivid demonstration of why you should probably never again step outside without it (via Laughing Squid, Co.Create).
