Code

Driver/development framework

Server running on node.js, control for any games using a browser window, interface with the wall using a C/C++ written node module.

Create online api for running code on the screen

It would be cool if people could browse to a site and enter code that they can run on the screen.

Great fun for teaching people about coding...

This does mean that you create a gateway for someone to run code on the server, and this code could be hostile.

How to keep it secure:

Software

Snake

A game of snake. This project is almost done. It just requires some more practical website for controlling the snakes (right now they can be controlled using keyboard, which sucks for smart phones). See Snake implementation

Super bomber man

No work done yet

Blocking issues

It is practical to only work on it after better abstracting the framework to be used.

Conways Game of Life

A cool screen saver.
