A structural wall unit system comprising,
- a plurality wall units each having a front face configured for substantially vertical orientation comprised of x primary rotational tessellation elements, where x is an integer equal to or greater than 1, and said primary element comprising a first irregularly shaped side extending in a generally radial direction relative to a first vertex;
- a second side extending in a generally radial direction relative to said first vertex and being rotationally spaced from said first side by a first angle of 360 degrees divided by n, where n is an integer greater than or equal to 3, said second side being substantially a rotational image of said first side;
- a third irregularly shaped side extending in a generally radial direction from a second vertex, said second vertex being spaced apart from said first vertex;
- and a fourth side extending in a generally radial direction from said second vertex, said fourth side being substantially a rotational image of said third side, said fourth side being rotationally spaced from said third side by a second angle of 360 degrees divided by m, where m is an integer greater than or equal to 2;
- and each side of said wall units having at least one spacer or connector configured to engage other said wall units;
- and
- a plurality of starter course units, each starter course unit comprising a portion of a said primary rotational tessellation element having at least one irregularly shaped side that is an image of said first side or said third side, each irregularly shaped side of said starter course units having at least one spacer or connector configured to engage said wall units, and said starter course units having at least one straight side;
- wherein said starter course units and wall units are configured for assembly as a structural wall having a natural, random appearance.
A three dimensional structural unit, comprising
- at least one face comprising a rotational tessellation;
- said at least one face having at least two irregular sides extending there from;
- and
- at least one of said sides having connectors adapted to align adjacent units.
A building unit system comprised of discrete, irregular, non-geometric units adapted to be fit together, said units comprising at least first units and second units, both of said first units and said second units having irregularly shaped sides, said second units being of a different size and shape than said first units, both said first units and said second units having sides that mate with other first units and mate with other second units, said first and second units being configured to mate with one another to form a continuous surface or structure without overlap between units or large gaps between units and having a natural, custom fitted appearance such that a regular geometric pattern is not readily apparent.
