Vat

Monza City Council banned curved fish tanks for pet owners, citing cruelty to goldfish due to distorted views. Are we sure our views are not distorted, like being in a giant fish tank ourselves?

Two worlds can be related through inclusion, intersection, or no intersection. Different worlds may have other laws, which raises the question of whose world is distorted. If we live in a "fish tank," does the outermost part of the world exist?

Scenario I
Fish tank
In this scene, the auditorium is situated in a hemispherical hood with a smaller ellipsoidal hood in the centre of the stage, and the actor will perform in an ellipsoidal hood.

Scenario II
Blending Separating
This space also comprises two spherical shells, like two bubbles about to separate.

Scenario III
Human Vat
As in the first two scenes, in this scene, audiences are in a
hemispherical cover, and actors perform in the space outside the cover.
