True. It most definitely of a mechanical nature but a typical user here would treat the commercial device as a chip - signal in, picture out. But those who would like to repeat Albert's Niptrix using this method and hand-building some 1500 of these mirrors instead of LEDs would certainly justify creating a "Mechanical TV" section.
It is very similar to the 2-axis single vibrating mirror method, which does have a proper name, I just can't recall it. One could view it as a parallel method as opposed to serial, and the light source doesn't require modulating.
