Loop-de-Loops and Squares

From Loop-de-Loops by Anna Weltman: https://recipesforpi.wordpress.com/2015/09/28/loop-de-loops-and-a-contest/ A loop is created like this: imagine you draw three segments as if partially going around a rectangle. a is the first side, turn left, b is the next, turn left, and then c. At this point though, turn left and go a units again... You can also try the instructions here: https://recipesforpi.files.wordpress.com/2015/09/loops.png In this case, I set a=8 and b=5. Then let c run through every integer from 3 to 13, for reasons of curiosity. I noticed a few interesting things... can you see them? Use the checkboxes to help you investigate. www.scottfarrar.com | https://twitter.com/farrarscott 2015-10-05
