A free, compatible alternative for 3Dconnexion's input drivers
Spacenavd, is a free software replacement user-space driver (daemon), for
3Dconnexion's space-something 6dof input devices. It's compatible with the
original 3dxsrv proprietary daemon provided by 3Dconnexion, and works
perfectly with any program that was written for the 3Dconnexion driver.
