Carlos sent us this interesting take on persistence of vision tech. This "low tech - POV spinning display" uses an arduino, paint roller, and the contact braids from a toy slot car. Clever design - those contacts act as an effective timer/trigger, simplifying the manual animation(aka - waving) process. - Link
