Scanimate! Source of nifty TV graphics

Have you ever wondered how they made those nifty animated TV graphics in the 70s/80s before computer animation? Here's your answer. Scanimate.
All done on a CRT monitor directly filmed or videotaped with camera kinescope style. The image on screen was distorted by one or more technicians until satisfied with the effect. Unless careful notes were kept, the same effect/coloring could not be produced again.
