At the Association for Computing Machinery (ACM) 25th Anniversary 
exhibit in 1996, in San Jose, California, one university project was 
demonstrating the overlaying of computed information.  Their demo 
goggles detected where they were pointed and generated the appropriate 
overlay.  The demo situation was large pieces for a space structure, and 
the overlay was things like arrows that showed which way to turn the 
screw threaded parts, and in which order.  Cool!
