The iPhone and smartphones in general have allowed us to capture amazing videos not possible with an old school video camera. One such incredibly cool effect was captured when one imaginative videographer decided to film himself playing his guitar from the perspective of inside the body of his acoustic electric six string. Thanks to the sensor in his iPhone he managed to capture one of the trippiest video in many years, the distorted motion of sound travelling through the strings.
Scientists at the Australian Nation University have this week released a video demonstrating their advances in perfecting a water based tractor beam. The ingenious system is able to move objects floating on the water without any physical contact, using only waves generated by complex algorythms.
