Hi Mike,

That idea was real cool. OK the contraption as shown by you will demand a tough mechanical setup for the inverted pendulum - but easy would be attach this LED column to a normal pendulum and "build" the whole thing on it. Even a mechanical "grandfather pendulum " clock would do. Maybe one can remove the hands and replace the dial with a simple digital display that is in synch with the pendulum display.. And the mounting of the LED column can be made to match with the background.

And someone was lamenting recently that "everything" that is there to invent / discover has been already done. NO.
