CrayonQuake is a custom renderer for the NPRQuake engine. The renderer gives the game the appearance of having been colored by a child. The work was intended to juxtapose the violent nature of the game with an innocent childhood activity.
Scene backgrounds are filled in alternating colors of crayon-on-paper like texture, with matching and interspersed highlighting borders.
The animated elements of the scene, such as weapons, enemies, and artifacts are rendered as if being colored continuously. Surfaces of those elements are drawn in an animated crosshatching style akin to the wall textures with polygon borders highlighted in a similar manner.
