Once in a while, a design pops up in my field of view. Eyebrows rise and I immediately try to figure out how it is built. Which symmetry group? How many lines? I spotted this vase from Paula Diaz-Sylvester on Facebook. A beautiful mesh that intertwines across the surface, entirely made up of circles.Continue reading
The original tessellation, with Arjen Robben as the “diver” was done in 2016, titled Gelbe Karte, or yellow card in German.

The FC Schalke 04 boys finally made me proud. They didn’t show any intimidation at playing the Bayern team. I am celebrating their performance with a tessellation of Schalke players. The ever polite Benedikt Höwedes, the powerhouse Sead Kolasinac, Gerald Asamoah a past icon of the club, and the referee, disciplining the ever-diving Robben, that’s the one dramatically grabbing himself in fake pain. Keep it up Boys, don’t stop! Continue reading
Took a while, but I finally came up with a tessellation I like, to represent this Pmm symmetry group. I’ve named it “Gelbe Karte”, yellow card. This tessellation is built with five characters, Höwedes, Asamoah, Kolasinak, the Ref, and the one receiving a yellow card for excessive simulation (diving), Robben. About time Arjen gets a card.
Deciding which symmetry group to use for a specific design can be hit and miss. And try again. You can narrow it down Continue reading
Group Pmm is also known as P2mm in Peter S. Stevens’ Handbook of Regular Patterns. A four-sided mirrored box. Figures with bilateral symmetry work best in this type of group. Continue reading
