Growing and Shrinking Machine

Summary
4 performers. 1 performer starts a scene, then another enters and the scene changes, then another and another. Then they leave in reverse order, and the scene regresses back to where it started.

It looks like this: P1           Scene A P1+P2         Scene  B P1+P2+P3      Scene   C P1+P2+P3+P4   Scene    D P1+P2+P3      Scene   C P1+P2         Scene  B P1            Scene A

Preparation
4 performers. 1 suggestion. 1 performer starts on stage.
