A story on slashdot today talks about a cluster driven CAVE setup and reminded me of last weeks discussion. Its not exactly what you were talking about, but I thought I'd pass along the link. http://www.isl.uiuc.edu/ClusteredVR/ClusteredVR.htm After quickly glancing through one of the papers, their approach seems to be to split the viewable surface into a whole bunch of individual screens, to which each node renders. Looks like fun. -mike
