The Department of Homeland Security has something they call the Threat Advisories, these come in 5 levels. Turns out some people would like to have one of these hanging on their wall so that they can crank up the threat level when they want to. Michal Zalewski thought it would be a good idea to make a display of his own, the display uses the same concept as the Word Clock we featured yesterday. Michal painted the back of some plastic black and then used a CNC machine to mill the letters into the painted side of the plastic to reveal the letters. The result is a very slick looking display that can easily be backlit using some colored LEDs. I can think of lots of cool uses for this technique!
Thanks for the tip Bob.
