EsCarGo is a mutant vehicle built by Piotr Brezinski and Kevin Byall, in the shape of a snail. The LED system was designed and programmed by Christopher Schardt. It debuted at Burning Man 2017.

1000s of LED modules cover the snail shell. The modules are attached to steel panels in a zig-zag pattern. The software that drives the LEDs displays two different kinds of scenes:

Pictures Scenes display images and videos more-or-less photorealistically. They use a mapping file that was generated by turning on one LED at a time while looking at the vehicle with the iPad’s camera, noting where each LED is in a given 2D perspective. Here's a video showing that process:  https://youtu.be/I5xe1rhLMAA

Stips Scenes send particles of color along lines that begin in the center of the shell and spiral outward. This involved a lot of brute-force mapping work, noting manually where each module string turned a corner on the panels.    

The computer program that controls the piece is LED Lab an iPad app that allows any image or video file to be used in creating animations. (City/country-specific imagery can be integrated into the performance.) This app is available on the Apple iTunes Store.
