This "electrochemical and electromechanical apparatus for the display of illuminated messages" is really a (heavily) modified persistence-of-vision toy. This toy was a pen i picked up at the local pharmacy (Walgreen’s) with a spinning head that displayed whatever message you programmed in. It was only $5.00, so i picked up a couple and let my imagination fly.
