Bo Preising, Suitable Technologies' vice president of engineering, seen on screen at center, and director of operations Milan Bhalala, far left and on screen at right, navigate their offices' recreation area using a Beam remote presence system in Palo Alto, Calif., Wednesday, Dec. 12, 2012. More employees are working from home, but there's still no substitute for actually being at the office. Enter the Beam.
