The seams stop being a problem
ProjectionA projection that resolves into a clean rectangle on a flat wall is a picture. One that breaks across surfaces, corners and seams is a cross-section.
The principle
You never see a higher dimension directly, only the slice of it passing through your plane. The photograph is a flat shadow of a built set, which is itself a staging of a life. The projection is a shadow of a shadow.
What changes
A visitor should have to move through the room to assemble the image, and should never hold all of it at once. Seams become the reason the image is worth walking around rather than something to protect it from.
Who it lands on
Not TJ. This changes what Carson's surfaces are for, and it makes the projection crop spec a creative brief rather than a geometry problem.
