Yes, I've used them.* But mine is more of a "test the technical
   limitations" type thing. I want a pixel-to-pixel, no compression
   correlation between pixel and voxel, all in a single image. In
   other words, if I hover over pixel 10028, 28394* and i do: /tp
   10028 65 28394 I'll end up in the same place.   I'm thinking of
   future compression-free computer technologies.* The compressions
   and shrinkings are so commonplace, we rarely stop to question
   the necessity.* But they're stopgaps, making-do while computer
   capabilities catch up to our needs. With enough capacity, there
   should be no need for such things, eventually.
