BB – a demo for Unix and DOS made by four Czech teenagers in 1997: Jan Hubicka, Kamil Toman, Mojmir Svoboda and Filip Kupsa. They made a notorious library for ASCII-conversion, AA-lib, which was later used for example in Hasciicam and VLC (see Wikipedia). They also made Aview that lets you browse the web in ASCII, ASCII-3D-2000 that creates stereogram ASCII, and more. It’s a similar spirit to the ASCII Art Ensemble.
