An up or down gesture on the screen changes the bend or 'sway' of the fractal trees. Side to side gesture changes angle between branches. Small gestures result in large changes!
Ceasing screen gestures will cause the app to return to the default, periodic swaying.
The 'settings' allow you to increase or decrease the fractal depth of the trees from 8 to 14 inclusive. The higher the number, the more aesthetic the display. However, the higher values require faster processing speeds to render smoothly.
Thanks to https://freesound.org/people/Setuniman/sounds/173067/ for the score and http://rosettacode.org/wiki/Fractal_tree#Java for the recursion algorithm.
Hope you enjoy and find a moment of peace with this app.
As always, I love to read your feedback and suggestions to improve this app.
