NimBorg is a library for accessing Lua and Python libraries from within Nimrod code. It wraps the C API of these languages with macros which make the code far more readable than the low-level API, and also automatically handles the memory management interface of these languages so that objects aren't deallocated as long as they're accessible from your Nimrod code.
Quizzley is a simple site that allows you to create a quiz or a poll and distribute it to your audience.

It's a fast way to interact with your audience; no authentication or registration are needed.
The Omega Project is a universe simulator accessible remotely by registered users over the JSON-RPC protocol. This allows the highest number of users and developers to access the universe and control ships / stations / other entities in via many mechanisms. The server listens for requests over a variety of protocols including TCP, HTTP, Websockets, AMQP, and more, and clients written in any language running on any platform may use these transports to communicate with it. Omega also ships with a WebGL frontend based on three.js, providing an interactive view into running simulations.
