What do you get when you take a motion graphics designer, an iPhone, and a dark room, and put them together with a Canon 5D DSLR? You get a new font named "Phone Streak," created by Marcus Byrne.
To create the font, Byrne set up the camera to take time exposures as he "light painted" the air with an iPhone. He painted not only upper and lower case versions of the 26 letters of the English alphabet, but numerals and punctuation marks as well. The short video below demonstrates how different versions of some letters were captured, and also how once Byrne had settled on the shape of each letter, he actually 3D-printed the "Z" (his favorite) as art.
