Esc drew inspiration from the French comapny EasyWeb, and vvvv.org's How To Project On 3D Geometry web page.
Esc modified and improved upon many of the techniques involved in order to ease setup for launch day. Also, since the university didn't have Windows machines, vvvv was not an option, and I took charge of figuring out how to do everything in OS X using Blender and Quartz Composer.

The most impressive aspect of Esc is the process by which we calibrated the video to match with the stairs. Normally, the exact location of the projector(s) and all of their lens properties have to be calculated in advance. The math for doing so is well over my head and since we were college students with limited resources we had no way of determining what combination of projectors we would end up with until the day of.
