This week, Laura Harms (Certified Zentangle Teacher in Saskatoon, SK) opened a weekly Zentangle challenge. The details of the challenge can be found on her blog, I am the Diva.
This week’s challenge is Simplicity. For this tile, I was inspired by Vi Hart’s Mathematical Doodles. It starts out with a singe closed line with lots of loops. It turns out that you can colour this image with two colours (e.g., black and white) so that sections of the same colour touch each other only at the corners. So while the result looks complex, the principle is very simple.
