Paul McCartney made his modest contribution to the future of virtual reality with a little help from a bike mechanic. The unlikely union of the Beatles great, a bike-shop employee in Palo Alto, and a promising if underachieving technology is the accomplishment of Scott Broock, once an enterprising executive with a fledgling camera company called Jaunt VR. In 2014, Broock offered to pay the mechanic $50 to ride around a skate park on a BMX bike while being filmed with a specialized camera rig that could shoot video and record sound in 360 degrees—all around and up and down.
