    Default Laser visualisation to lead to better speakers?

    This came through my email today, thought I would share as it's pretty cool.

    that was awesome, you can see when the sweep hit the crossover point

    you learn to deal with directional sound... I have electrostatic speakers, pretty much as directional as it gets

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    Hehe, WTF?

    I prefer the Canadian trailer-park saying that goes "Beware the pitter-patter-of-the-shit-a-pillar".

    Hmmmm, that's interesting am i right in thinking he is effecting the deflection with the sound or just the beam intensity.

    Could be quite a cool effect to place a pair of Piezoelectrics in the beam path, I have to try it.

    Actually, I had another thought, wondering what the beam would be like if you place a mirror on a Piezoelectric transducer, maybe a very small deflection but then add some lens setup to expand the angles. Change the frequency of the drive to the transducer and don't we end up with a fast as hell scanner?

    Isn't this essentially how the audience scanning beam brush works to reduce power density?
