Ceiling fan POV display
This display is made out of 32 LEDs for each propeller's blade (5 in total) which means that some kind of multiplexing is used to connect those 160 LEDs to microcontroller. In this case, 8-bit shift registers 74HC595 that transform serial-in data into parallel-out data were used, and microcontroller is Atmel on Arduino platform. The good thing about this POV is that ceiling fan does not produce any noise as motors in every other POV display we have seen so far.
