Make it pass as something else.
Plaster painted as marble.
Seen in Duane Hanson, Museum Guard, 1975
Try it on your work
Make one thing on your table pass as another thing on your table, using only its surface: wrap, paint, position. Stop when a person who did not watch you picks up the wrong one.
Write a paragraph in a form it is not: a recipe as a legal clause, a memo as a prayer. Hand it to a reader without saying which. Stop when they name the wrong form; if they name the right one, revise once and hand it back.
One person carries on a full exchange with a third in the manner of someone else present. Stop when the third addresses them by the other person's name, or catches it; either ends the round.
How it has been used
Make one thing pass for another: plaster painted as marble, the decoy duck on the pond, the prop letter that reads as real on stage. The move forces a witness: a disguise that fools nobody, or that nobody sees, has done nothing, and the test is whether someone takes it for the other thing.
