If you can find an old Philips top-loading laservision player, these
had a nice he-ne laser, and a neat 2-axis voice-coil mirror actuator
assembly. Ideal for displaying pretty patterns, especially
lissajous-type circular shapes, but won't move fast enough to do text
etc.
Last time I looked, the pros used very expensive galvanometer devices,
driven hard (& requiring extensive damage protection) for beam
scanning.
