Span is an advanced Connect Four-like game for the console, written in Ruby.

Features include:

1. Console. Pure ncurses. No need for fancy X servers, you can play it over your favorite SSH connection.
2. Unlimited players and board sizes, though it may get unwieldy (or even strategic) after you add more than a few.
3. AI play for those lonely, cold winter nights.
4. Programmable AI contestants.
5. Network play, because the AI isn’t always friendly.
6. Nifty colors and a sweetass logo.
