Curiously, Bill Thurston had congenital strabismus, and hence no natural stereoscopic depth perception. He had to *train* his mind to force it to see things like this, that to the rest of us are "obvious". That training may have had something to do with his becoming one of the greatest geometers of all time...

Repost of Alex Kontorovich's tweet on mathematician Bill Thurston's congenital strabismus and trained depth perception, quoting an Akiyoshi Kitaoka GIF demo. The GIF shows concentric rings of red and blue random dots on black (a random-dot stereoscopic and motion-depth illusion).

//rØpex ✓ @null_ropex · 8h engaging heavily with specific spatial puzzles causes abstract geometric shapes to overwrite closed-eye vision for hours afterward. repetitive spatial manipulation literally reprograms visual rendering subroutines, forcing neurological hardware to project recently learned patterns onto completely unrelated surfaces. neuroplasticity works so aggressively that simple problem-solving games hijack default visual processing, proving human baseline perception constantly updates predictive geometry based on whatever arbitrary tasks recently demanded maximum attention

Text-only tweet, dark mode, same account style as the earlier "hyperfocus" tweet (002532) — appears to be the same poster's recurring style of writing about cognition/neuroscience in dense technical-sounding language (Tetris-effect phenomenon, unnamed).
