> if you can imagine an IMAX screen wrapping all the way over your head you are on the way.

Those actually do exist! [1] That picture isn't great, but if you search for "Imax Dome" there's some videos and stuff. I still remember watching a movie in one that was kinda like an early racing drone flying through a canyon and being awed as a kid.

They're projector based, rather than curved screens. The first one was built in the 1970s.

The Sphere probably still blows it out of the water specs wise, but more people than you'd think are familiar with the "surrounded by the image" phenomenon.

Wait, I thought the dome style was IMAX? What is a non-dome Imax theater like then?

A big flat screen. Indianapolis had both curved (Children's Museum) and flat (Indiana State Museum) IMAX theaters for a while, but the Children's Museum got rid of theirs and put a dinosaur exhibit in the old dome.

Someone might be from San Diego!

The dome-style IMAX are actually apparently quite rare, the "normal" IMAX is just a really big (about three stories tall) screen, that is slightly curved usually.

I believe Six Flags over Georgia had an actual IMAX dome that I remember as a kid - a projector experience of short films such as flying airplanes, racing cars and such.
