They weren't screaming with you: they were screaming at you 
The Vector Flier looks like it was built around something other than a standard video display. Is that the case? If so, is it something the home hobbyist could build inexpensively? I really like the looks of it: it brings back fond memories from the 1970s, when I was working for a university, and got to play with many neat toys, including a Tektronix vector graphics terminal that was way ahead of anything generally available at the time.
