TUNDRA
Readableimage
TUNDRA is a graphics format and is one of several systems for expressing text-mode graphics using text characters and control characters setting positions and colours. ANSI Art was the main system of this use, but a few others were invented during the Bulletin Board System (BBS) era. The ansilove (and Ansilove-C and ansilove.js) open-source software can display TUNDRA among other formats, by converting ANSI/ASCII art to PNG images.
