A knitter sees a mitten in this graphic, while a crocheter, a nifty potholder.
A quilter sees a block pattern, while a tiler, a stove backsplash.
A graphic designer wonders what software lead to this image, while a computer program thinks about code.
Are you surprised that I made this with a spreadsheet?
A twodimensional sequence of numbers leads to this image. I layered a series of triangles on the number pattern. Coloring only odd numbers yields this graphic.
The mathematics behind the triangles within triangles connect to many things. The probability of coin tosses. Fibonacci numbers. The dreaded binomial expansion of Algebra II lore. Things forgotten but can be reforged (the sum of a geometric sequence).
What do you want to create with this pattern?
How would you change it? Download this file (the one on the left), print, and start coloring. Or, download the image (the one on the right) and use a painting application. However, there is something satisfying in doing work of the hands.

I decided to try both ways, and I learned some things. Permanent markers bled too much, and crayons worked much better. Working by hand required greater attention than computer graphics because mistakes on paper are harder to fix. Using crayons tapped into tactile senses. Handwork takes longer and requires more patience. In a world where fast is coveted, coloring with crayons felt relaxing and is probably easier on the eyes. Computer graphics offered more flexibility: I played around with a couple of color combinations before I settled on one.
