Motion capture technology is the stuff of magic. I learned this firsthand when I put on a black onesie interspersed with sensors, waved my hands in the air, and watched a frog on the screen next to me do the same. Everything I did the frog did too, with the accuracy of my own shadow. Then Jakob Balslev, founder and CEO and of motion capture suitmaker Rokoko, replaced the frog with an old man in a wifebeater, who mirrored my behavior with a scowl on his face. Motion capture this good usually costs hundreds of thousands of dollars, which is why it's typically relegated to high-profile Hollywood studios and well-established game designers.
