ASCII Spinning Donut

is a classic ASCII animation that renders a rotating 3D torus using nothing but characters. Watch the donut spin in smooth loops as shading and depth turn plain text into a surprisingly solid 3D shape. It’s a nerdy little demo that proves text can do 3D.

Original concept credit
The spinning ASCII donut (3D torus) concept is widely known online and is commonly attributed to Andy Sloane, who popularized it through his “donut.c” demonstration. This version is an independent reimplementation with its own code, controls, and presentation, and is not affiliated with the original author.
