Hidden Swirls

This is my second entry to the May's Formula challenge held by heavenriver which you can find here  Ultra Fractal monthly Challenges Redux ~ Vol. 52.

May's Formula challenge will be the Semi-Regular Tesselations challenge!
In this challenge, you MUST use any of the Semi-Regular Tesselation mappings in sam.uxf on ALL layers, none excluded. Mappings other than Tesselations are also forbidden. The formula and colouring algorithm, instead, are entirely up to choice! Be sure to show the actual tesselation pattern in the final fractal, though. Multiple mappings can be on the same layer as well, so long as they are still Tesselations.

Thank you so much for all your favs, comments and support.
