Architecturally, it is so simple.
You go in, and you go in, and you go in.

Rectilinear planes and frames are raised to different heights.
The structure has no curves or tricks of folding: you must provide those yourself.

You circumambulate and enter, you fold and enter, you become the needle trailing your fourth dimension.
