Visual display device

A visual display device, comprising

• a plurality of blocks in next-adjacent side by side relation, each block being of substantially equilateral triangular cross-section and having two opaque sides of trapezoidal configuration, a third at least translucent, colored side of rectangular configuration, an at least translucent base of equilateral triangular configuration and an opaque top of isosceles triangular configuration, the base being substantially perpendicular to the three sides and the top triangle being at an angle of inclination with the base and having an angle at the corner joining the two sides of trapezoidal configuration and an opposite side coincident with the top edge of the third side and farther from the base than the angle;
• and
• a plurality of light means each at the base of a corresponding one of the blocks, said blocks being arranged with said third side of at least one of said blocks adjacent a trapezoidal side of another of said blocks, such that light is transmitted only through said translucent third side, so that an opaque top of a given block derives colored light from adjacent blocks and not directly from the light means at its base, said translucent colored third side of at least one block being of varying color with respect to other third sides of said plurality of blocks.
