ABSTRACT:
An amusement device includes a thin strip wound into a coiled configuration and selectively extendable axially into a tubular spiral configuration tapered from a larger end to a smaller end, the strip having a light-reflective arrangement for reflecting light radially inwardly such that upon viewing a patterned target through the tubular spiral configuration, from the larger end toward the smaller end, multiple reflected images of the pattern of the target on the inner periphery of the spiral configuration provide amusing novel optical effects.
