The use of modelling structures as visual aids, finds application in areas such as : architecture, engineering and the many sciences - to childs play with sand castles at the beach.
This toy construction element was envisaged as being made up of three face attachment areas. Having a mirror image : so as a left and right handed example are to be had. Placed and attached - wired, glued, welded or affixed most any way - face to face : typically in alternating sequence, right handed element joined to left, to right, etc.
Wire frame structures ; The attachment areas have curved surfaces, so as to allow degrees of movement off centre. Thus two elements can join in different perspectives via the same face attachment.
Combining toy construction elements may simulate static atomic element positioning, relative to lattice structures.
