Damn, that would be good fun, although moire patterns might be easier.
Coming from the graphics industry, I’m very familiar with moire patterns. I’m wondering if there might be a way to reproduce the phenomenon within the eye/brain system, rather than outside it.
Back to the double slit experiment, if each pupil acted as a “slit”, what wavelength and distance might a light source need to be to try and replicate the interference patter within the brain? Assuming this hasn’t already been attempted before, of course.
