Thank you for opening this line of thought, Laurel ... Many more parameters beyond the visible were not mentioned in this show and await exploration -- someday even by Science, when appropriate measuring devices become available. In regard to sacred geometry, energetics, and creation of sacred spaces, also see Freddy Silva et al.
I wish to add that portable 'sacred spaces' (altars) are used by many religions, from the simple two-dimensional icon, to small boxes that open to display diorama-like displays, to three-dimensional spaces (by placement of drawings, candles, rocks, etc. ) that can be set up anywhere. Also immediately comes to mind a portable labyrinth I have walked - drawn on a large piece of cloth, placed on a floor during its use, and then easily rolled up like a rug for transport to a new location or storage.
