This is pretty cool. I'm curious, what do you mean "leverages your brain's spatial memory"?

Yeah, I don't know about the author, but my brain spatial memory is very much tied to Euclidean geometry. The holonomy effect (view is rotated when coming back to the same point) in particular is very disorienting. It's cool, but I would never use this for real.

I think it means you remember things by where they are relative to each other.

But yeah, the rotation effect makes it a bit confusing compared to normal space.

I really like this, but moving around a bit I find that things kind of seem to rotate which is disorienting. When this loads, the photo is to the right of the cake. After zipping around a bit in this space, the photo is then to the left of the cake. Is that a rotation? Is there a way to lock the orientation?

Ah, just found the node that says that "there is no up/down/left/right".

I do not understand this space.
