Abstract: An amusement device according to the invention offering numerous possibilities for mapping data with results, for example, drawings, mathematical functions, names and the like depicted on visible surfaces (6, 16, 24, 25, 34, 35) which are adjacent and rotatably or revolvingly movable. The device includes a base unit (2) with a visible surface (6), carrying several rotating elements (10, 13, 17, 19, 21, 23), two of which have visible surfaces. Angular locating means (41-46) are arranged on the surfaces for displaying the data and results and for matching pairwise. Fixed ratio kinematic connections, especially gears, transmit rotations between rotating elements and manual driving means (8, 11, 14).
