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.
Holographium is available from the App Store. It’s completely free until November 15th, 2010, and will be priced at around $10 after that date.
