When I made this piece some years ago and named it “The Sentinel,” I had forgotten that was the name of the original 1948 Arthur C. Clarke short story that was the inspiration for his 2001: A Space Odyssey. Not exactly the same geometries, but still apropos, I think.
“It was only a matter of time before we found the pyramid and forced it open. Now its signals have ceased, and those whose duty it is will be turning their minds upon Earth.

– Arthur C. Clarke, The Nine Billion Names Of God, “The Sentinel” , (New York: Signet – Harcourt Brace Jovanovich, Inc., 1974) p. 227.
