For guitarists and non-guitarists alike it’s interesting to see what the inside view looks like when a guitar is played, but to top it off, Youtube user justkylevids put his iPhone 4 inside of his acoustic guitar and started to play it. Interesting enough, the way the iPhone 4’s camera shutter works it captures video of how the strings oscillate (or vibrate). The guitarist explains:

I just happened upon this trick when testing what it was like filming from inside my guitar. Note this effect is due to the rolling shutter, which is non-representative of how strings actually vibrate.
