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. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
