Place a digit on each hour of a clock and read the number as the path that visits them in order. 123456789 walks neatly clockwise; 151515 snaps back and forth across the dial. The circle turns a number into a pattern you can read with your eyes.
Create a Number Circle maps the digits of any number onto a ring and connects them in sequence. Choose a clock dial or a full ring, pick the circumference, and every batch number becomes a labelled constellation you can copy or download.
