und aus dem Chaos kam eine Stimme, und die Stimme sprach zu mir
"Lächle und sei fröhlich, denn es könnte schlimmer kommen."
und ich lächelte und war fröhlich
und es kam schlimmer.

Nibbles was a Snake-like game, which was part of MS-Dos, as an example file for QBasic. The name "Nibbles" (probably ?) came from the half-bytes - "nibbles" - since on the terminal, it uses characters that split every terminal character into two parts.

Well, there are a lot of newer Snake-like games out there. However, the special thing about cNibbles is that it is, as the original Nibbles, a pure terminal application.
