Thanks to oktobor for supporting the TIG
Though this visual quirk would be interesting:

It seems like human vision adapts based on the level of contrast in a
scene.  For example, if you've been wearing lab goggles for a while and take
them off, suddenly the world will look like it has 'super high' contrast
(super high being a technical term of course).

A related/similar form of adaptation (and possibly the same???) is
demonstrated at the following website:


It's sort of like the trippy red/magenta balls discussed a while back, but
in black and white.  It seems that the contour adaptation is a localized
effect that doesn't happen across your entire vision.
