This is a collection of GNU/Linux software tools to implement a virtual-reality system for biomedical research. It makes use of the Blender Game Engine to drive an immersive spherical dome projection system (more information on Paul Bourke's site; the dome projection mode was integrated into Blender by Dalai Felinto).
See GettingStarted and DomeProjection. A simple Blender game that can be controlled with two optical mice is available. I'd be happy to add electrophysiology, dome projection etc. if there's enough interest.
A turnkey version of the spherical dome projection system, based on our design, is commercially available from PhenoSys.
