when the technical staff from the Academy Awards called us a few days before the Oscars we got to work making a custom prompter for their spec:  it had to fit through a 12" wide gap at the front of the stage and be robust enough to travel on a track beneath the stage and be lowered up and down for the talent.  The result was a small rugged prompter with 10x10" glass based on our QPRO series teleprompters.  You can see the little guy with Sony box camera and Fuji lens attached at the front of the stage.  Many shots were done through our US made low-iron 65-35 glass, it looked great and met the specs required for this world-wide broadcast.
