An idea for a 3-segment display (using rotation!)

A cool idea for a 3-segment display possible by rotating the display. Though this seems unrealistic, I bet someone could make a clock that very quickly rotates the segments. (I think this has already been done, so its definitely possible!)

Thanks to @CompactStar for suggesting that I try my idea with a 3-segment display. Thanks to @luxfundred for getting me interested in segmented displays. ... https://www.youtube.com/watch?v=-swF1yM6hKw
