**Recommended Materials and Processes:**

ï· Computer with internet access

ï· 3d modeling software (or download my design for free)

ï· access to 3d printer (I use Shapeways.com)

We experience our lives in 3 dimensions. Einstein showed we live in 3 spatial dimensions with a 4th dimension of time. This is the spacetime continuum. The 4th dimension upon which this instructable instructs is the spatial 4th dimension.

Dana Carvey as "the Church Lady" used to ask something like, "isn't that spatial?" Indeed it is.

Were we stick figures living out our lives, strolling around on a sheet-of-paper Universe, it would be maddeningly confusing for someone to elucidate the "3rd dimension" to us when our entire culture has been defined by "up" & "down", "left" & "right".

Nonetheless, we can do it. Should we wish to transcend the limitations of these measly 3 dimensions we must consider that which we have not previously experienced, back on the sheet-of-paper Universe.
