Not in my flat world! None of this spinning round and around business, thank you very much!
My rectilinear sun would light up in the morning and traverse along the two precision ground hardened steel rods located at the poles.
At the end of the day the sun would be extinguished, allowing time for maintenace crews to change out any LEDs which had failed. Once the essential maintenance was done, the crew would push the sun back to its starting position, ready for the next day.
