A Light Bet

Driving downtown, Liz and I spotted the most recent sign on the Blue Cross/Blue Shield building.

Known for its custom messages, the two of us argued about how the messages were “created.” Liz felt that it was a more manual process (turning on specific office lights by hand), and I was convinced it had to be a more automated one (involving a central computer or laptop that handled everything).

Apparently, I’m totally wrong. While there is a computer involved that handles the color of the lights, everything is apparently done by hand.
