After photographer Ross Ching came across Dentsu London's creative 3D light painting technique with an iPad, he decided to give it a try, combining it with timelapse photography to make a music video for "I'll Try Anything Once" by The Strokes (seen above). The app he used was Holographium, which you can pick up for $5 from the app store.
Back in September we featured a creative technique that used an iPad to "light paint" 3D objects and text. Now there's an app called Holographium that allows anyone to light paint words with an iPad, iPhone, or iPod Touch. All you do is provide some text, start taking a long exposure photo, and then drag your iPad (or whatever iDevice) through the photo while the app slowly displays the various slices of the text. The resulting photograph will show the text spelled out in 3D and floating in the air.
