The Sketch-A-Graph had two expandable arms on a trellis-like
arrangement; One arm held a pen and the other a plastic pointer. You
moved the pointer and traced out a drawing, and the pencil moved
likewise. You could magnify or reduce the resulting drawing by
changing where on the concertina-like trellis you connected the arms
and pointer.
I had one of these and it was impossible to use due to the Flimsy
70's plastic design which meant the trellis often fell to pieces and
had to be held together with yards of sellotape, and the fact that
the suction cup thingy would never attach itself to the table
properly, needing nine inch nails to hold the thing onto your
mothers favourite antique dining table!
