Spike Field
https://nsite.buildtall.systems/spikefield/

Code: MIT, as the project (see ../LICENSE).

The concept is Michael Brill's "Spike Field" (concept and art by Michael Brill; art by
Safdar Abidi), one of Team A's marker designs in Appendix F of "Expert Judgment on Markers
to Deter Inadvertent Human Intrusion into the Waste Isolation Pilot Plant", K. M. Trauth,
S. C. Hora and R. V. Guzowski, Sandia National Laboratories, SAND92-1382, November 1993,
a United States government work. The measures of the Keep, the berm and the repository
horizon are from "Permanent Markers Implementation Plan", DOE/WIPP 04-3302, August 2004,
a United States government work. No drawing is reproduced; the geometry is this project's,
computed in projects/blender after the concept.
