Circular Recursive Drawing

I took the reworked Pythagoras tree (which worked with angles) and modified it a bit further in order to change the resultant image completely.

After I saw that it works, I experimented a bit with random variables, lengths and angles until I created something I had on my mind in the first place — circular drawings.

Examples

These examples show how sensitive the whole piece is… Even a slight change of initial variables can cause a totally different outcome. This one and only line of code caused all the differences we can see above:

var a = 45 + i * range.value;
