Girl Guides have their own version of t

Girl Guides have their own version of the Poincaré disk model, where the {4,4} tiling approaches infinity in the center of the disk? Or is this a circle inversion applied to the {4,4} tiling? What's going on here? Please help me understand this!

(Whatever it turns out to be, nice work 10th Ipswich Guides!)

Seems related to the material in (an old web page of mine; these days I would have put the same thing in a blog post)

Spiral Tilings

I realise that by allowing for kites instead of rhombi in my zomes app, and by setting the height of the dome to zero, I already had a tool for playing with kite tilings:

It is, essentially, the {4,4} tiling wrapped through two diagonals, up to homeomorphism.
In other words, glue the two red lines in a way which identifies the two arrows, apply a conformal transformation, and you get the tiling.
