Abstract
A flexible flag has a plurality of spiral shaped wire elements carried by the flexible flag body. The wire elements are mounted for rotation about generally parallel axes along a vertical support. Gearing between a motor and the elements rotates the elements. The elements have portions spaced from their end portions offset from the axes of rotation. Those elements are in phase or out of phase relative to one another. Rotation of the elements causes a rippling or waving effect in the flag simulative of a flag waving in the breeze.
