Provided are cubes from which composite structures may be produced.
Composite structures constructed from a plurality of cubes according to
the invention are useful as an instructional aid to students for enabling
them to readily visualize front perspective, end perspective, and
overhead perspective views of complex geometrical shapes. Visualization
of such perspective views enables students to more readily produce
drawings of such perspective views in paper renditions of such views, and
exercises the three-dimensional thinking centers of the brain.
