The grids grew out of an element created for the Square Dance series. This element immeidately prompted thoughts of tesseracts (hypercubes).

I have come to question whether the space beyond the three physical dimensions can be experienced dimensionally rather than only conceptually. Consider our ability to experience two-space - that flat piece of paper is really a three-space object. The best we can do is the mobius strip. This wildly three dimensional form is the best, perhaps only, physical manifestation we have of two-space with its one edge and one surface of flatness. From this, it makes intuitive sense that the term "physical dimension" may not apply to two-space any more than to four-space, assuming it exists.

If the four-space does exists, then is our universe an odd object within that realm, similar to the mobius strip within our three-space realm? Imagine yourself as a being within the two-space of a moobius strip. How would it be?* Are we similar creatures as them, except we are looking from three-space to four-space and beyond?

 

* In 1884, Edwin A. Abbot published Flatland, in which he describes the society of plane shapes in a "broad and wide" world. Abbot's is more social commentary than an attempt to examine the experience of a two-space realm. In its broadness and wideness there is an implication of a third dimension. My feeling is a being existing in the two surfaces of the twisting Mobius is something entirely different than the idealized projections of Platonic solids in Flatlands.
