  • 1985: A brief, transient outbreak of Geometrical frustration affects nuclear reactors around the world. The outbreak will last only a few microseconds, and there will be no signs of damage to any of the reactors. The event will later be recognized as a precursor to the Chernobyl disaster.

  • 2018: Steganographic analysis of Spiral Rings 2 reveals "at least five hundred megabytes of encrypted data." Cryptographer Janet Beta calls it "a completely unexpected treasure-trove of archaic Gnomon algorithm functions, some of them timestamped centuries ago, which raises interesting questions of provenance."
