Designer Marcus Byrne of Melbourne, Australia created a 3D letter and font suite using the light from an iPhone.
Byrne created the Phone Streak font in darkness by painting characters in the air with the light from the iPhone. He photographed the light streaks in 3.5 second exposures with a Canon 5D camera.
According to the artist’s page on Behance, the project started as an experiment on turning hand waving gestures into a 3D object. Byrne decided to create a working font suite that he would give away for free.
Byrne made the resulting font, which resembles thick brush strokes, available for free on Dafont.
