A mod that adds 40 luminous sign items to Minecraft 1.20.1+. This mod is based off Ron Cobb's visual design work for the movie Alien. Each sign is designed to quickly indicate an area's purpose with simple iconography instead of complicated diagrams or text requiring multiple translations.
Each sign is assembled from a painting and one or more mundane items or dyes. Each sign can be duplicated with a regular painting to save on further resources, and each sign can be also crafted back into a regular painting should it need to be recycled.
The colorscheme used comes almost exclusively from the Tango palette.
