This is an old project that seemed halted by refusal by DLP to provide a DMD chip
to vastly increase the 3D resolution. This project has not changed at all since
before HDTV even existed. I suppose after people realize the world isn't flat, this is what
they will watch when 1800's movie technology finally gets "old".
It is simple enough to have been built entirely by not more than 2 people, in a very short
total amount of time.
It actually does project animated 3D bitmapped images into the air.
It can be made by anyone who is good at PIC programming and mechanically inclined.
It cost us NOTHING, and has potential beyond most high budget 3D display research.
It contains no parts that were not available in 1980. All were scavenged from a junk pile.
Most or All of it's 3D animations were sent 100 miles over a 14400 baud modem.
It does not stop if the modem hangs up.
It looks the same from all angles.
It has no mirrors, just one lens, which doesn't have the size limitation of a parabolic mirror.
It's a hunk of junk, but it works.
IT IS PUBLIC-DOMAINED (cc-share alike)
And, should the info be updated, a solution to the failure to acquire DLP may be included.
As well as some more of the animations that are stored in it.
That's an old 80286 laptop, used as a TTY on the right.
