Build: POV (Persistence of Vision) Display

Here's a build of a POV or "Persistence of Vision" display using the LEGO MindStorms Robot Inventor set.   With one motor affixed to a center base, the hub spins around while showing different patterns of the LED lights. Conceptually, it should be able to display the word LEGO or any other words or patterns, especially when run in the dark.   It needs a faster motor or gearing up to make the POV display much better.
