The NUI file format is a structured image specification developed by the Nuru project for encoding terminal-based graphics and cellular data. It is primarily used within the Nuru ecosystem to store character-oriented artwork, including specific color palettes and spatial layout information for command-line environments. Although considered a niche format for terminal art, it is generally safe to handle, provided that compatible viewers are used to parse the internal data structures correctly.
