Revisiting an unravelling

This is based on an old pattern where I took a clockwise loop of 6 pentagons and combined them with two counter clockwise loops of 3 hexagons resulting in a clockwise loop of pentagons and hexagons. One way to think about the process is to imagine unravelling the loop of pentagons. I used this pattern back in back in 2007 and 2006 but this one has a bit more of a twist.
Perhaps I should come up with a visual of this unravelling. I was hoping I would find one in my blog but I didn't. I should make a better index for this thing...done. In this screen capture, you can see that the outside of the original pentagon loop is now the inside of the composed shape and the inside of the original loop corresponds to the 4 sides of the pentagons the are on the outside of the composed shape. Perhaps I'll play some more with this ‡(double dagger shape which I found its html code here).

Zig, Zag, Zog

Here's just a bit of play before I head to Basketball. I call it zig, zag, zog because there are 3 chunks to the code. Usually, I have a standard zig-zag pattern alternating between to 2 chunks of code. But there are three loops: one if made of zig and zag, another is made from zig and zog, and the final is made of zag and zog. Not too deep but still nice with my new SVG output.
This picture of the code shows a as zig, b as zag, and c as zog. It's pretty clear that a calls b which calls a making a zig-zag loop; and similarly that b calls c which calls b making the zag-zog loop. But the zig-zog loop takes a bit of though--in the code for b since it calls both an a and a c. But essentially c results in a cbcbcb loop with that last b also calling an a so the first c essentially calls an a. Similarly a essentially calls an c thus resulting in the zig-zog loop. There's a bit of twisting calling going on.
