AAlib is a libary to render images as (monospace) text characters, so graphical applications can be viewed in a console. Needless to say it's fun, rather than useful.

Many Linux video players can use the library, and there even a version of Quake linked against it.

An example of AAlib in action (as you can see, the effect works quite well with big Anime eyes):
