An extendable split-flap display!
Connect any value to the rerouter and it will display it with physical bricks and not any of those newfangled "Point Lights."
You can extend the display's amount of digits by placing them next to each other, slightly overlapping so that the rerouters overlap and automatically connect.
A split-flap display, or sometimes simply a flap display, is a digital electromechanical display device that presents changeable alphanumeric text, and occasionally fixed graphics. They were (from the 1960s to 1990s) commonly used as public transport timetables in airports and railway stations. (Wikipedia)
