Girih Appさんのイラストまとめ

@HypercubicPeg As always:
The hardest part is choosing the colors.

@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.

@Tyson_Ritter @MrJohnRowe All the #PatternLunch patterns can be created with the @GirihApp and exported for example as SVG or PNG file.

@PaulaKrieg @mathhombre @Desmos @kathyhen_ @jensilvermath Something similar made with the @GirihApp :

@Simon_Gregg @geogebra or with @GirihApp … :-)

Every tiling in the paper „Some Monohedral Tilings Derived From Regular Polygons“ by Paul Gailiunas can be drawn with the @GirihApp .

@Simon_Gregg @zarahkhussain Yes. With cool 1/12 angles.

Different colors for the same pattern.

@wasanp_ Crescents tilings work also for even numbers of edges. But for 6 a chessboard coloring ist not always possible. But with 8 it works fine.

@wasanp_ You can create those crescents from any regular polygon with an odd number of edges >= 5.
