64pixels is a multiplayer open world game that offers a comprehensive set of tools for constructing just about anything a player can dream of. Best described as an ASCII version of Minecraft, this versatile program has a crazy number of features for you to play around with, and clever folks can even build things like the electrical circuitry seen in the video.

There's already a multiplayer server in place for players to connect to (megairc.org), and pressing the T key allows you to chat with other people on the same server. While in chat mode, typing /who also brings up a list of players.

Windows and Linux builds are available to download from official site, and if your internet browser is capable of running Java applets then there's a page that you can visit and play the game from inside your browser window as well. A tutorial that explains most of the GUI and menu options can be found here. (source: jeb)
