Making images using information from keyboards, controllers, motion sensors, and acoustic instruments

With Funk's system, viewers witness multiple perspectives while moving, just like the hologlyph, thus integrating it fluidly into the real world. "This is a cheesy example, but everyone knows it," he says, with more energy than a mere cafe americano can provide. "Imagine Clint Eastwood when he says, 'Go ahead, make my day.' What if you were watching that movie for the first time, and right at that scene you're looking at the back of his head because you can — that takes away a lot of effect and power from the filmmaker. It's not a bad thing or a good thing. It's just a different art form."

Hologlyphics illustrates the potential for enhanced viewing experiences and new ways to tell stories. "The thought of it is very common, but the existence of it is not," he says. "I think once this stuff does exist, there's no putting it back. It's like Pandora's box — people are gonna love it."
