langtons-termite is an implementation of Langton's ant that runs in a terminal emulator (see also Turmite). It uses Braille Unicode characters to display a high resolution bitmap. Some fonts support this effect better than others.
This program is part of a project that explores implementations of Langton's ant on multiple platforms (Classic Mac, Commodore 64, and a modern terminal emulator). See the article at nybble.org for more details.
Terminal: Gnome Terminal, Font: Anonymous Pro
