A johnny-five, event based, traffic light disco for your Arduino. An array of lights flash in majestic sequence for your gyratory pleasure. Each light's shining heralds it's own destruction, each extinction seeds a new. Just like the traffic light eyeball cannons of your friendly neighbourhood mobile DJ
