absolutely fascinating - thanks

I particularly appreciated the 'stereo kinetic' effect (No. 3), as I only see out of one eye

Speaking of which, I've heard of one-eyed airplane pilots .. do you have any opinion on this? Apparently no-one has depth perception beyond about 20 feet or so .. so would it mainly affect landing and near passes? How do they get by?

I'd appreciate your opinion, as I've often wondered about this ..
