Randy Powell's 2010 talk mentioned in the article, on "Vortex Based Mathematics" - the secret of the universe, free energy, cure for all diseases etc...
"Essentially, the idea revolves around a circle with nine points equidistant from one another. Number the points, and then draw lines connecting each vertex n to its double modulo 9. ...You get a vortex! Sort of. ...Rodin claims that it is the "Mathematical Finger Print of God", which is of course a perfectly reasonable assertion for a mathematical paper to make."

Sadly, it appears not to be a clever hoax but an actual Thing.
