Is it real or just French humor?
If not fake, an amazing demo illustrating how you could conceivably get alternating-frame/frame sequential 3D without shutter glasses by modulating the eyelids.
Probably belongs to the ‘don’t try this at home’ category?
How long can you use this without damaging your eyes?
Would you be brave enough to try it on yourself?
Can nostrils be modulated for stereo smell?
I still prefer head mounted displays for true stereo, motion tracking and the full immersive 3D experience.
