Abstract
A device for creating an illusion includes a helix and an object in an arrangement which gives the illusion that the object and helix move relative to one another as the helix is rotated. The helix can be flexible or of a stable configuration such that it can be free standing. Support for the device can include a base or a swivel arrangement for suspending the device. The device can be free to rotate in moving air and, in situations where there are lesser amounts of air flow, a fan can be attached to the helix. Where there is an absence of moving air an electric motor can be employed. Variations in the arrangement and size of the components of the device can create variations in the illusion of relative movement. The use of colors and materials which glow in the dark in situations where there is low light, along with variations in lighting, will also vary the illusion of relative movement.
