Each book in “For Pittsburgh” has about 450,000 characters, and will take about 20 hours, on average, to cycle through the LED tubes. Each side of the display has about 750 tubes stretching from the bottom edge of the convention center’s roof up to its peak.

The letters, about 3-foot-high-by-1-foot-wide, scroll vertically up the horizontal tubes, which are about 2 inches wide, 14 inches long and spaced about 7 inches apart. —Patricia Lowry —Blue light special of a different kind tells a good story (Post-Gazette)

Sounds like a cool installation… it’s at the David L. Lawrence Convention Center, in Pittsburgh.

Credit for suggesting this one goes to my wife.
