Thanks guys, plenty of ideas to run with there.
Stephen : The electrical discharge circuit might prove problematic. I would think the ozone produced would be a bit of a health hazard in this age of Health and Safety.
Dr Z : Your display device is in fact in use on buses here in the UK. The destination board is made up of a matrix of small 5mm discs which are painted fluorescent yellow to one side, the reverse being black.
I'm not sure of the mechanism which is used to flip them over but it seems to be a left to right movement across all columns together.
Kind regards,
GL
