CGLX

CGLX is a cross-platform cluster graphics library originaly started in UC Irvine by Dr. Kai-Uwe Doerr, Prof. Falko Kuester and Prof. Stephen Jenks. It is currently actively developed in UC San Diego. It is a very powerful OpenGL framework. Any application written in GLUT can be relatively easily changed/recompiled to be presented on the display wall such as HIPerWall.
