Fractal Zen 1.6.4 APK

Tilt and turn your phone or tablet to generate a smooth flow of beautiful fractal patterns. Lose yourself in the infinite intricacies of the Julia Set. There are no points to score. No goals. No objectives. Just take a moment to relax, let go, and enjoy the beauty and wonder of mathematics. Like a virtual fidget spinner.

This app turns your phone into a glowing, ever-changing gem, a digital kaleidoscope of swirling recursive tendrils. Explore the various shapes in different areas of the motion space. Do not try to hold on to a pattern - there are infinitely many more.

The Julia Set is a simple function that generates unending fascinating images. Coupled with your phone's gravity sensor, it becomes interactive. The Julia Set is related to the more well-known Mandelbrot Set.
