I had an interesting experience in that area a few years
ago. One of the entries in the PyWeek[1] game programming
competition was a platform game set on the inside of a
circular world. You saw a small part of the world at
a time side-on, with the ground curving up slightly
to the left and right.

After playing for a while, my brain must have trained
itself to see the curved ground as straight, because
when I looked away, all horizontal straight lines
looked like they were curved *downwards* slightly!

[1] A competition for Python-based games, so getting
a bit closer to being back on-topic.
