A snail spiral based on a series of equilateral triangles. The series is different from the Fibonacci series, but similar: 1,1,1,2,2,3,4,5,7,9,12,16,21,28,37,49,65,86.114,151,200

I thought I'd start to share some geometric tiling patterns.
This one is a spiral of five arms, made with decagons inside of kites.
