libtermboy

libtermboy is a graphics library for the Linux console. No, it's not an ASCII art library like aalib or libcaca. With libtermboy, you can draw pixel-perfect images in a text mode terminal.

To see the magic in action, clone the repository and execute make run. Use ←/→ to move and press ESC to quit. If your sound is on, press A-G for an extra surprise!

The documentation for the most useful functions can be viewed by running man doc/termboy_screen.3 (or just look at the source, it's not that long...).
