Excellent exercise for building environments and object work. Ask one player to start doing an activity that somehow defines (broadly) a location. E.g. when someone starts typing she might be in a (home) office. The other players then become the other objects in the environment.

Notes

Tell the first player she can start using the props built by other players in the environment (if she recognizes them). Tell players to go for the obvious: in just about any room you could be a plant, a door or a table, after all.

When done, ask the first player to name any `object` built in the environment.

Variations

You can use this as a handle for a performance. When a player is asked to sit down, and there are no chairs on the scene, another player can become the chair for the first player to sit on. Other examples are ticking clocks in haunted houses, cabinets and closets, you name it.
