At first glance, the black rectangle in Scott Griffith's hands looks like a bumpy piece of plastic.
But those bumps are really LEDs: light emitting diodes. It's those diodes, spaced a centimeter apart, that will light up in a few months and display highlights, statistics and advertising to Springfield Falcons fans when they take the ice at the MassMutual Center in downtown Springfield.
The black rectangles each have their own bit of computer circuitry and fit together to form the 18-foot-by-12-foot scoreboard panels that will be hung in a four-sided box over the ice.
Curved pieces go on the corners and wide strips of LED display go on the top and bottom for constantly rotating words and images. The whole thing gets topped with permanent light-up signs lettered with MassMutual Financial Group's logo.
