The Ouchi illusion generates subjective motion.  Different sizes of the Ouchi
illusion have caused five students who see colors when listening to music to see
different colors in all three sizes of the illusion.   An electronic enlargement
of the illusion could be a useful tool in your research.   About one in ten will
report color in one of the sizes of the illusion that I used.  The colors
reported are not the same for different individuals.
