Semiotic Signs
by Arborwatch
Semiotic Signs is a Forge decoration mod that adds 40 luminous sign items with simple iconography, inspired by Ron Cobb's visual design work for the film Alien.
What it does
Each sign is meant to show what an area is used for with a plain pictogram, so a reader can understand it at a glance without a long text or a diagram. Several signs are drawn from the painted, flat look of Ron Cobb's design work on Alien, and the color scheme leans almost entirely on the Tango palette. Because the designs carry their meaning in shapes rather than words, they avoid the need for multiple translations.
The signs are built from a regular painting and one or more mundane items such as dyes, so the mod reuses materials players already gather. A sign can be crafted back into a regular painting, which means the painting is not lost when a sign is made and the resources can be recycled. Installation needs only Forge, and the mod runs on client and server, so the server and every player need it. Files cover 1.20.1 – 1.20.6 under the WTFPL, which is not an open source license.
