  Speaking of which this brings to mind another old
project idea I had that
 never went anywhere.  That was using a 3" scope tube to "write" to film,
 and then after developing,  to read it back again.  I vaguely recall
 "flying spot scanner" being somewhat related to this,  I think there was
 some equipment out there that'd actually take a 35mm slide.  Though I'd
 envisioned a roll of film,  driven by a stepper motor. 
 Ever hear of the IBM 1360 photostore?

 It was used a verb at Lawrence Livermore--as in "Your file has been
 photostored."  A very unfortunate happening... 
Wow!  That's one of the coolest things I've ever seen.  Are any of them
still around anywhere?
