Connected prism elements swivellingly

Claim 1

An amusement device, comprising: (a) a plurality of hollow prisms rotatably connected in a series; (b) each prism having two right angled triangular sides in parallel planes, a rectangular base, and first and second square sides, wherein the first square side is the front of the prism, the second square side is the rear of the prism and the prisms are connected in front-to-rear abutting relation; (c) a plurality of substantially semi-spherical projections formed on the outer surface of each abutted first square side; (d) a cylindrical swivel joint base extending fom the center of the outer surface of each abutted first square side, wherein each abutted swivel joint base has a square projection located thereon with a first hole formed centrally therein; (e) a plurality of depressions formed on the outer surface of each abutted second square side; (f) a second hole formed at the center portion of each abutted second square side, wherein the second hole diameter is substantially similar to the diameter of the cylindrical swivel joint base such that the second hole is capable of flushly receiving a said cylindrical swivel joint base; (g) a washer having a diameter greater than the diameter of the second hole and having a third hole formed therein which is square-shaped and is capable of flushly receiving the square projection formed on the swivel joint base; and (h) a screw having a head diameter greater than the distance between two opposing sides of the third hole, wherein when the cylindrical swivel joint base of a first prism is received flushly by the second hole of a second prism and the square projection on the cylindrical swivel joint base of the first prism is received flushly by the third hole of the second prism, the threaded area of the screw passes through the third hole of the second prism and into the first hole formed in the first prism, such that rotation of the first prism relative to the second prism rotates the screw and washer in unison therewith.
