This add-on set contains an additional seven pieces (one per color). Here at MathArtFun, we understand it takes more than 35 tiles to cover the infinite mathematical plane. All of the pieces together cover an area around 9-10 inches across. The pieces are laser cut from 3-mm-thick acrylic. In the image here, the blue tiles are flipped over, and each of the other six colors is given its own rotational orientation. The set contains five pieces in each of seven colors. This puzzle consists of 35 tiles that all have the same shape – the recently discovered monotile that only tessellates aperiodically (in non-repeating fashion). Available for pre-order now expected to ship around April 15. All the pieces together cover an area around 9 inches in diameter. You can select mostly blue (only mirrored tiles green), mostly green, or 50/50 (half green, half blue).

The pieces are 5-mm-thick EVA foam with magnet backing. Six of the tiles in this set are mirrored, indicated by the backside (flipped over) shirt graphics. A small fraction (around 13%) of the tiles must be mirrored for the tiling to work. This puzzle consists of 42 tiles that all have the same shape – the recently discovered monotile that only tessellates aperiodically (in non-repeating fashion). The Escher-inspired puzzles on this page were designed by Robert Fathauer to fit together in many different ways, while nearly all of Escher's designs fit together a single way. Escher was famous for his tessellations using recognizable motifs such as lizards and birds.

All of the tessellation puzzles on this page can be be assembled several different ways, making them open-ended and encouraging creativity.
