Trefoil knot as trackplan?

Since writing about Bill Schopp's investigation into trefoil layout boards I've been looking online now-and-then for information about trefoils.

One interesting page I found was this one on trefoil knots. It got me thinking that trefoil layout boards are all well and good, but the important thing is having an interesting track plan running on them. I started wondering if any of those knots could be the basis of a trackplan. Clearly they  would need to be adjusted to account for the physical realities of track. They also might have a bit of the 'rabbit warren' about them, but for something like a Mt. Lowe inspired layout, that might be a good feature to have. 

Anyway, I parked those thoughts until last week when Voie Libre #115 dropped in my mailbox. Inside there's a gorgeous HO-9 circular layout - size unspecified, but it might have the same diameter as an extra-large pizza - by Frédéric Blandel whose trackplan seemed to me like a variation on one of those trefoil knots. Here's a side-by-side comparison of the layout's trackplan against one example knot:

M. Blandel's trackplan is not a pure trefoil knot, but it certainly appears to be in the spirit of one. It's ingenious and allows for both continuous scenic running as well as a little switching fun for when the mood strikes. And there doesn't appear to be a need for overly complex wiring as there are no reversing loops. This layout might be thought of as a trefoil knot trackplan on a circular board. It might be interesting to see what a trefoil knot based trackplan on a trefoil board would look like.
