A true 3D display based on a vibrating mirror was designed by Larry Sher and built at BBN Corp. many years ago. The system is called "Spacegraph" and only a few were sold. Spacegraph satisfied Bob Bickford's definition: "A true 3-D display would have the characteristic that you could move your head and/or walk around it to see more information." I have no idea if Spacegraph was the first operational system to satisfy this definition, but I've copied Larry on this message and he may add more.
