Rob Joyce’s (@RGB_Lights) wife thinks he has a problem. He has been building computerized Christmas light shows for the last five years, adding new elements every year. His most recent display was likely visible from the international space station. In addition to an infatuation with Christmas light displays, he helped a Boy Scout troop built catapults for the annual Punkin Chunkin competition until lawyers ruined it for all of us. To pay for these hobbies, he works as the White House Cybersecurity Coordinator and has led organizations at the NSA doing both foreign intelligence and cybersecurity work.
