Here is an update of the hopf node, with the tennis ball curve equation corrected, and hooked up.
It is currently set to 3 lobes, with only 3 "90ish degree" "network curves. For 4 lobes, only 3 "90degree" network curves are made, with one differently sized...
I'm going to learn how to do a dozen or two dozen of these "90degree" network curves, in nodeeditor, probably for only one lobe, and try out network.
Also the number or angles are to be made compatible with the number of lobes...
