This is me…
The right hand image is conical mirror anamorphosis . If you click here sample python code to generate it from a photograph. I wrote the code for the Fete de la science three or four years ago.
In 2014 the theme was crystalography so with my colleague Romain Joly we set out to explain tilings. Click here to see some of what we did.
Here are some other samples: - On the left a photo of an adaption by Jerome Malmaisonasse of a
at the FabLab of a file I prepared. - On the right an svg source file that you can download and cut if you have access to a laser cutter.
And perhaps the most famous of M.C. Escher’s tilings

With Herve Pajot we have been testing geometric teaching materials. On the right is a decomposition of a large square into two smaller squares as such it is a “geometric” proof of Pythagoras’ Theorem. In fact there are many other such constructions listed here and this is number Proof #76. On the left is an svg file for laser cutting.
This kind of construction is related to the technique used in the paper to answer Calegari’s question in this paper.
