ABSTRACT:
An amusement or educational device comprising a plurality of interlocking collars, each including gaps, and slidable along and rotatable about a common shaft. The common shaft bears element of a multi-relationship about its circumference in sections of the shaft corresponding to each interlocking collar. The gaps in the interlocking collars selectively expose corresponding elements of the multi-element relationship. In one embodiment, the collars are configured to allow users to construct fortunes, words, sentences, equations, or other relationships by selectively interlocking adjacent collars to expose word, mathematical, sentence or other appropriate elements disposed around the shaft.
