All of a sudden something interesting appeared! - imagine a scrolling LED sign, without any LED's, this brought up 2 questions, what/how?  anyway your
thoughts would be nice to read :)


I recorded the video from my phone, take a look...

Maybe they had a paper tape with holes in it for the letters...similar to the technology invented by Mr. Jacquard in 1801.

All you need then is some photo resistors and a bank of vacuum tubes connected to light bulbs.
