What is MPE and how does it work? From mostpixelsever.com:
The Most Pixels Ever library is a software solution for taking a single-screen real-time graphics application (developed in Java) and spanning it across multiple screens (each connected to a separate computer). Its features include “ time syncing” and “ spatial syncing.” Time syncing ensures that each frame is rendered simultaneously on each display and is achieved by network communication. Spatial syncing ensures that each client computer renders the appropriate portion of the larger display on its display.
