FireBlu is an animated texture from Doom and Doom II: Hell on Earth that is notorious for being perhaps the most ugly texture in the game. On top of its general lack of reason, it often causes eye strain with its bright and contrasting colors.
FireBlu Jam is a Quake mapping jam centered around the texture. Mappers were given from the 8th of August until the 15th to create whatever map they wanted with only one primary rule: Their map must feature FireBlu prominently!
