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.
Gespeaker is a GTK+ frontend for espeak. It allows you to play a text in many languages with settings for voice, pitch, volume, and speed. The text can also be recorded to a WAV file for future listening. Gespeaker supports the speech synthesizer MBROLA for a better speech experience.
