Ok, I am going to wallow in my geekiness. I went ahead and bought a Pro-Lite led marquee Model PL-M2014RV6 (aka Tru-ColorII ) on eBay for 150 hard earned American dollars.
I mounted it in my cube, connected it to the serial port of my computer and proceeded to hack together a perl script that talks to it. Easy enough. Then I innovated (in a Microsoft meaning of the word) – wrote a script that parses our weblogs and outputs what people search for on the marquee with fancy dissolve effects. Add a couple of lava lamps and it’ll be just like Googleplex.
I read up on Pro-Lite programming on this website, but ended up not using any of the code from there. Also some of the information there is outdated – the ROM on my sign is version 6.5
P.S. For those of you who are wondering, “tru” colors are: red, orange, yellow, lime (!) and green. They come in dim, normal and bright varieties, also rainbow, red/green, red on green and other combinations. All other colors are not “tru”.
