Quick 720p@60 fps capture of Akronyme Analogiker's entry for the PC 4k intro competition @Revision 2013. It's a brute-force spheretracing raymarcher that accumulates the distance estimations along the ray to emulate some sort of X-Ray look together with heavy prostprocessing (noise, tv-lines and color abbreviation with lens blur) timed with some nice 4klang synth.
