Yeah, me too, but my impression is that they're only for pre-prepared
displays, and only some displays (notably those that don't involve the
beam turning any sharp corners, such as Lissajous figures).
My impression may, of course, have been - be - incorrect, which is what
I'm asking for; if you've seen such displays involving sharp-corner
turns of the beam and run-time chosen displays, then obviously my
impression is incorrect and the technology exists.
