Box Quilt

Saw this lovely quilt. Thought about what if the squares turned, so I set it up to interpret numbers between 0 and 1 as turns of the square. The function counts the rows and columns from 1 to n as x & y. I set up the crosses to be multiples of the square radius, but I should have made it up to a standard distance..
