Feziii, a new tangle
Was just playing with my tangle Zello (find the step-out here) when I had this idea, and out came a new tangle, just like that.
This is definitely a new approach to a tangle: the first step creates a shape with 4 main sides, then a shape with 3 sides, then 2 sides, and then 1 and 1 and 1.
4 -> 3 -> 2 -> 1 -> 1 -> 1
Here you can see that FEZIII (which is the closest to the 43211 that I could think of) is quite different than Zello, and I felt it deserved a whole new name.
I really love how 3-dimensional it is, even with all those straight lines. And the shading was easy -- a bit time consuming -- but gave me some really good moments of Zen Flow.
Here is a before and after shading example:
