Times table on a circle
The Times Table Hides a Heart (and 200 Other Shapes)
200 dots on a circle. Each one is joined to its k-th multiple — and k keeps climbing. At 202 the heart is back and the loop starts again. Multiplication, drawn.
The rule
Join each point n to point n × k around a circle. One multiplication draws a cardioid and its cousins.
