Abstract
Abstract A device for producing a block-built picture comprising a plurality of blocks and a support for mounting the blocks in a regular arrangement along coordinate axes. The blocks are adapted to present varying pictoral elements of at least one area thereof to define a picture perceived by the areal density of the pictoral elements. Thereby a block-built picture is produced by properly selecting the area of the pictoral elements of respective position of cubic blocks or changing the rotational position of cylindrical blocks.
