Sandia National Laboratories' tiny micromachines now have a spokesman who's bigger than life. Charlton Heston provides onscreen and voice-over narration for a promotional video about micromachine and integrated microelectronics R&D performed at the lab. (Also, see Design News, 3/2/98, p. 126.) On the video, Heston taps into a half-century's worth of performing experience about the role of microsystems in nuclear weapons surety and other applications. The video conveys a sense of wonder about the engineering genius behind mechanical devices too small to see, but big enough to perhaps change the world. "Heston become fascinated with the technology, really amazed with the way we make these things, and what they might be used for," says Paul McWhorter, deputy director for the Technology, Microelectronics and Photonics Center at Sandia.
