Nexus is a general purpose host for several experimental games. It handles communication with an H-ITT remote control base station, player avatar assignment, game configuration management, and general game settings. Wiimotes may also be used as controllers if a Bluetooth adapter is available.

• Pixel - a cooperative art program where players create a shared picture on a black and white grid.
• Flatland - a game played on a two-dimensional grid where player avatars move around and possibly interact.
• Group Sum - a collective binary search problem where players try to guess a random number as a group by summing their individual guesses.
• Forager - a game where players compete to acquire the most food before the game ends.

Nexus and all games are written in C# for the .NET platform. Specifically, Nexus uses the Mono GTK# libraries for its user interface (http://mono-project.com/GtkSharp) and the games use OpenTK (http://www.opentk.com) for all graphical needs. Other libraries include HITTSDK (a .NET wrapped for libh-ittsdk), Apache log4net for logging (http://logging.apache.org/log4net/index.html), NDesk.Options for command line parsing (http://www.ndesk.org/Options), and NPlot for Group Sum's graph rendering (http://netcontrols.org/nplot).

Nexus is meant to be build on a Unix-like platform, so Makefiles are used. In addition to the master Makefile in the Nexus source directory, each game has its own Makefile. A Visual Studio 2008 solution file is included, though it does not copy all necessary files to the output directory (see the BUNDLED_FILES macro in the Nexus Makefile).

The default target in the Nexus Makefile will build all games and the Nexus binary. The "clean" target will delete the Nexus binary and the "mac" target will use Mono's macpack utility to generate a Mac-compatible .app bundle with everything inside.
