The visuals on the first one are cool, but it has me thinking more in the lines of new speaker technology. As an example: The media (I am guessing salt) that they are using to form the visuals gives you the different patterns on the plate (if the salt wasn't there, the patterns would still be there, just invisible). If you could apply this principal to a different type of media rather than a solid plate, lets say a material flexible that could be used for a speaker cone, Then lets say for your guitar cabinet, not only would you have your regular input for the speaker, you would have this second frequency input attached directly to the cone material that you could adjust the frequency to. It would almost work like a tens unit on one of your muscles. The higher the frequency applied to the cone the stiffer it would become. This would allow you to totally change the tone of your speaker with the turn of a knob? Sorry for the rambling...
