This cleverness makes me think of Russell Brown getting frisky with a flashlight & Photoshop Touch. Colossal quotes creator Michael Langan as saying,

Most of the video is lit by a single flashlight, drawn slowly over the landscape and later “echoed” up to 500 times to create patterns that fill the scene with light. We used a projector mounted to a motorized lazy susan to achieve the “sliver” shots of Nicole.
