We’re able to do amazing things thanks to technology nowadays. However, I think the best results are achieved when technological progress and creativity work together. The video below is a great example of that. You’ll never believe what an iPhone and a regular guitar can do. This guy in it wanted to record a video that showed his passion for music and had the most brilliant idea: to put his phone inside his guitar. Thus he managed to create an awesome illusion. However, the strings aren’t coiling as they appear to in this video. The illusion is actually caused by a side effect of camera sensor technology known as “rolling shutter”.
