Do not forget one of the (IMHO) best features of the NeXTdimension board -
the real-time video compression! Not only would it be able to produce those
images of snaking jet streams (albeit using a different method), it can/will 
combine the video compression with renderman (i860) or live video (video in) in
ways that make multiple LUT's look like a childs toy...
