@johncarlosbaez This Penrose Triangle is part of the example menu of the @GirihApp.
It can be used as starting point for more complex possible and impossible shapes.

Writing a chapter on aperiodic tiling I've fallen in love with Penrose tiles all over again. Here are patches of both the kite-and-dart and rhombi versions of the tiles. The markings enforce matching rules.
The @nytimes for kids holds a writing contest! Draw your pen (while I draw my penrose)

This is an example of a Penrose tiling: a special kind of tessellation that is “non-periodic”. Even though it consists of just a few different shapes, it never repeats itself. https://t.co/IgPclxTG4v
