Making Virtual Solid (MVS California) Our breakthrough was accomplished by applying our knowledge of several seemingly-disconnected areas of engineering to produce a new and powerful technology. Chris Grabowski and Tom Zamojdo have been engaged in car navigation projects for more than eleven years. The Virtual Cable was conceived in 2001 when they realized that a GPS-enabled Heads-Up-Display could be far more effective when reduced to just a single line, but only if such line was displayed in true volumetric 3D. Applying Chris’ knowledge of advanced laser optics and Tom’s knowledge of real-time computer software, they developed a commercially feasible design for a 3D HUDs. Chris and Tom reside in San Francisco.
