4th annual World Tessellation Day. Begun in 2016 by Emily Grosvenor for M. C. Escher's birthday. (More of that story and Emily's book.) Don't think I'll get a chance to make a new tessellation for today, but here are some of my favorites from the past year. (Mine followed by the real treats from others.)
Mine:

| In Isometric |

| GeoGebra applet |

Others':
- David Petro's double translation tessellation in Desmos
- Regolo double rotation elephants.
- Marcelo Henrique Tatuador's cool graphic 2 tile.
- Diego Lieban's sweet animation of a classic square alteration.
- Hidekazu Nomura is a great twitter author of many figurative and geometric tessellations. Like these kites.
- Jason Panda's awesome Batman.
- Must visit: Craig Kaplan's Tactile applet
- Gábor Damásdi's fascinating quadrilateral. (Made me make this applet.)
- Tim Lexen's tiling lenses. (Which made me make this applet.)
Not nearly everything you could see. Do you have a favorite - list it in the comments, please! If you have ideas for a GeoGebra applet, I'd love to hear it.
To explore further, there's a tessellation page on this blog, or a tag on my tumblr, or GeoGebra books for (mostly) tile altering tessellations and Islamic Geometric Patterns.
And happy WTD. Go cover something with a finite set of shapes and no gaps or overlaps! Might need to work on a better slogan.
