A block as recited in claim 1, in which said inner wall is of light-passing character, said subject matter including art work formed on said inner wall and following its recessed contour, and there being additional subject matter behind said inner wall and visible therethrough.

Claim 10

A block as recited in claim 1, in which said block has two generally parallel corners formed along opposite sides of said outer wall, said opposite sides of said inner wall being received and retained within said corners respectively.

Claim 12

A block device having a plurality of generally planar outer walls defining together in cross section essentially a polygon with corners formed at the junctures of said walls, a plurality of inner walls inwardly opposite said outer walls respectively and each recessed progressively away from the associated outer wall between two opposite sides of that inner wall, adjacent ones of said inner walls having portions thereof projecting into common ones of said corners in mutually abutting and supporting engagement, at least one of said outer walls being transparent, and the associated inner wall carrying subject matter to be viewed through said transparent outer wall.

Claim 13

A block device having a plurality of generally planar outer walls defining together in cross section essentially a polygon with corners formed at the junctures of said walls, a plurality of inner walls inwardly opposite said outer walls respectively and each recessed progressively away from the associated outer wall between two opposite sides of that inner wall, adjacent ones of said inner walls having portions thereof projecting into common ones of said corners in mutually abutting and supporting engagement, at least one of said outer walls being transparent, and the associated inner wall carrying subject matter to be viewed through said transparent outer wall.

Claim 14

An essentially cube shaped block having four essentially planar transparent outer walls with four essentially parallel corners at the junctures of said outer walls, four inner walls located inwardly opposite said outer walls respectively and having opposite side portions projecting into said corners respectively, each of said inner walls between its opposite sides being recessed progressively inwardly away from the corresponding outer wall so that as it advances from one side thereof to the other the inner wall first advances progressively away from said outer wall and then returns progressively theretoward, at least one of said outer walls being transparent, and subject matter carried by the associated inner wall and visible through said transparent wall.

Claim 15

An essentially cube shaped block having four essentially planar transparent outer walls with four essentially parallel corners at the junctures of said outer walls, four inner walls located inwardly opposite said outer walls respectively and having opposite side portions projecting into said corners respectively, each of said inner walls between its opposite sides being recessed progressively inwardly away from the corresponding outer wall so that as it advances from one side thereof to the other the inner wall first advances progressively away from said outer wall and then returns progressively theretoward, at least one of said outer walls being transparent, and subject matter carried by the associated inner wall and visible through said transparent wall.

Claim 16

A block as recited in claim 12, in which said block has a transparent end wall, and an essentially planar sheet at the inner side of said end wall and retained between it and said four inner walls and having markings visible through said end wall.

Claim 17

A block as recited in claim 12, in which said one inner wall is transparent or translucent, there being subject matter behind said one inner wall and visible therethrough.

Claim 18

A block as recited in claim 12, in which said one inner wall is transparent or translucent, there being subject matter behind said one inner wall and visible therethrough, and carried by another of the inner walls.

Claim 19

A block as recited in claim 12, in which all of said four outer walls are transparent and all of said inner walls carry subject matter visible through the associated outer wall, each of said inner walls being of inwardly bowed progressively curving configuration with said subject matter including art work following the bowed curvature of the inner walls.

Claim 20

A block as recited in claim 12, in which all of said four outer walls are transparent and all of said inner walls carry subject matter visible through the associated outer wall, each of said inner walls being of inwardly bowed progressively curving configuration with said subject matter including art work following the bowed curvature of the inner walls, said block having two transparent top and bottom walls, and sheets at the inner sides of said top and bottom walls and carrying markings visible therethrough and retained thereagainst by said four inner walls.

Claim 21

A block as recited in claim 12, in which all of said four outer walls are transparent and all of said inner walls carry subject matter visible through the associated outer wall, each of said inner walls being of inwardly bowed progressively curving configuration with said subject matter including art work following the bowed curvature of the inner walls, said inner walls being translucent or transparent to enable viewing through one of the inner walls of some of said subject matter carried by another of the inner walls.

Claim 22

A block as recited in claim 12, in which all of said four outer walls are transparent and all of said inner walls carry subject matter visible through the associated outer wall, each of said inner walls being of inwardly bowed progressively curving configuration with said subject matter including art work following the bowed curvature of the inner walls, said inner walls being translucent or transparent to enable viewing through one of the inner walls of some of said subject matter carried by another of the inner walls, said subject matter including objects secured to and projecting from both the front and rear sides of said inner walls.

Claim 23

A block as recited in claim 1, including an additional wall located between said inner and outer walls and recessed progressively away from said outer wall between said opposite sides of the inner wall, but not as deeply as said inner wall is recessed, and thereby located rearwardly of the outer wall but forwardly of the inner wall, said additional wall being transparent or translucent to enable viewing therethrough of said subject matter carried by said inner wall, and there being additional subject matter carried by said additional wall and spaced from both the inner and outer walls.

Claim 24

A block as recited in claim 1, including a sheet of material extending inwardly from said outer wall in a direction generally perpendicular thereto and at an end of said inner wall and having an inner mirror surface facing toward said inner wall and reflecting said subject matter.

Claim 25

A block as recited in claim 12, including four transparent or translucent additional walls each located between an associated one of said outer walls and the opposed inner wall, said additional walls being recessed progressively away from said outer walls, but not as deeply as said inner walls, and therefore being spaced from both the inner and outer walls, said additional walls being transparent or translucent and carrying additional subject matter spaced from both the inner and outer walls.

Claim 26

A block as recited in claim 12, in which said block has an end wall, and an essentially planar sheet at the inner side of said end wall and retained between it and said four inner walls, said sheet having an inner mirror surface facing said inner walls for reflecting said subject matter.
