Rotational device

A rotational device for tangibly experiencing movement of a three-dimensional object in four dimensions, comprising:

• an outer frame comprising a plurality of wires forming a three-dimensional structure defining an interior of the outer frame, wherein the wires are arranged in spaced-apart configuration with one another enabling visibility of the interior of the outer frame from outside the outer frame, wherein an outer side of the outer frame defined by outer sides of the plurality of wires is shaped as a sphere, and wherein the plurality of wires extends along a plurality of great circles of the sphere;
• and
• an inner cubic frame assembly movably mounted for rotation within the interior of the outer frame, wherein the inner cubic frame assembly is visible from outside the outer frame, and further wherein the inner cubic frame assembly comprises a cubic frame and a sphere mounted within the cubic frame.
