Create Celtic Knots

To artists and mathematicians, knots can be beautiful, interesting structures. Until recently, I hadn't explored them much from either perspective. Then my mother-in-law gave me a copy of George Bain's...

Try out Triknots

Our first knot puzzle was based on Celtic knot designs that begin with a square lattice, with diagonals representing the rope of the knot. The Celtic artist selectively replaced intersections...

Barnsley Ferns in the workshop and on the stage

Dylan Thurston connected us with Melissa Freilich at the Ann Arbor Civic Theater, who was directing Tom Stoppard's play Arcadia. Because of the fractal themes in the play, Melissa wanted to...

Inspirations

Many of our products are based on ideas we have serendipitously bumped into and found attractive. But we also hear from people who help us create a new product, or...

Try to tesselate with Corona Tiles

We were recently introduced to an interesting area of tiling research by mathematician Colin Adams. This is a story about tiles that can fill the plane, tiles that clearly can't,...

Golden b: aperiodic with one shape

At a JMM conference, mathematician Keith Copenhaver called our attention to Robert Ammann's Golden b tiling. It is unlike the tilings we see around us every day. Most tilings are...
