Alex,
A dual head machine is not the answer, I tried this already
with my Tornado 3000 card. Java only sees one GraphicsDevice
with a dual head card. You need to be able to access 3 different
frame buffers to create the 3 different GraphicDevice objects needed
to set up a CAVE.
You can do this with Windows 2000 but I dont think you can with NT unless
someone out there knows how.
