I say this video is fake. 3 main reasons: 1) The frequency (seen in the video as distance between peaks and valleys) does not change much at all with the change in fretted note per each string up and down the neck. Neither does the waveform (which is incredibly unrealistic) 2) The magnitude at which the strings are vibrating is so severe they would be colliding with each other and causing significant buzzing or noise 3) The extreme right angles and other sharp angles the strings display in the video are completely unrealistic. People claim to have tried it and say it's real. I say it's a bunch of crap. It's either a complete creation using video software, or the effect of a digital artifact caused by the video software on the phone. What says you!?
