ETIPADO: Extremely Tall Image Processing And Display Object
Home: California, United States
ETIPADO: Extremely Tall Image Processing And Display Object is a startling demonstration of the persistence-of-vision effect: Shake your head "no" at a strobing column of light and images appear out of nowhere. Interact with the work by making faces in the work's camera, while friends see you in the strip of LEDs in real time. What's happening? The LEDs display vertical slices of images in fast succession. As your eye moves across the piece, the two-dimensional image “burns” into your retina, one column at a time. Sophisticated processing software takes real-time imagery from the attached digital camera and broadcasts them to the LEDs. ETIPADO is unexpected art: It’s easy to walk by and not notice it. Once discovered, participants are inspired to share the “secret” with those around them.

What Inspired You to Make This?
I've been fascinated with persistence-of-vision displays since I was a kid, having seen small single-color examples for many years. Once full-color addressable LEDs became ubiquitous, I wondered if this effect could be achieved with color images. The next logical step was connecting a digital camera to see if the software I wrote could display the images in real time. It works!
