Actually, some of the SGI's can do more than 24 bit color. I forget if it
is 32 or 64 bit, but I know its more than 24 bit. I had the same discussion
with a few friends, "Could you feasibly ever need it or use it?"  We couldn't
really think of any applications for it. We got this information from a catalog
from Silicon Graphics. It does indeed exist..... (Those guys are crazy! :)
