Who doesnt love frying their arduino by applying 12v to the 5v rail.......damnit.......

Disclaimer: I use an All-In-One for my main computer at work, the laptop the VGA is connected to is ARCHAIC and for some reason wont let me mirror the desktop. The best I can do from work is display the background color on the LED, Screensavers are poo and youtube is soooo slow on this thing its terrible.

Well, need some more funds to replace the arduino..... But I will take this home tonight and see what it looks like running on a good system. I was thinking, maybe if its too choppy I could add capacitors in parallel with the wire running to each base, small ones, to create a slight fade, instead of an abrupt chop chop chop.
