Fractal LW Bundle Donation

SaK-RFHY

About this app

Enjoy a collection of fractal & math based wallpapers.

This is a Donation Version of the bundle, there are no differences between this and the free version. This version may get new features faster though :)

Currently there are five wallpapers:
Bifurcation Diagram (Canvas & OpenGL)
L-System Generator
Mandelbrot Set (New)
Plasma Tunnel
Sierpinski Triangle
Sierpinski Gasket

Bifurcation Diagram uses the Bifurcation Equation to create a series of lines. Open GL version has options for types of objects and transparency/blending.

L-System Generator creates line diagrams based on rules. Presets include Koch Snowflake, Dragon Curve, Gosper Curve and many others including a manual option. Rendered in OpenGL.
- Tap on the right or left of the screen to spin the system.
- Uncheck Draw All in settings to watch the L-System draw each segment.

Mandelbrot Set allows zooming into any location to a high magnification in OpenGL.
- Tap on the settings button to enable the tools
- White rectangle is the zoom area
- Plus Magnifying Glass zooms in
- Minus Magnifying Glass zooms out
- Floppy disk save to the current Mandelbrot to SD card
- Red arrow resets to the initial Mandelbrot zoom
- Second toggle allows the increase or decrease of iterations of the set (more iterations will slow rendering but give more detail in certain areas)
- Saved Mandelbrot pictures contain the coordinates and zoom factor in exif data
- Setting toggle button can be disabled in the wallpaper settings
- Multiple color schemes are also select-able along with other optimizations and Deep Zoom mode

Plasma Tunnel creates a multi-colored tunnel out of a shape. Rendered in OpenGL.
- Tap on the right or left of the screen to spin the tunnel
- Tap on the top or bottom of the screen to move forward faster or slower

Sierpinski Triangle uses an equation to draw a triangle on the screen.
- Tap on the screen to clear the triangle

Sierpinski Gasket uses an equation to draw a pyramid similar to the triangle. Rendered in OpenGL.
- Tap on the screen to rotate the gasket.

Try out the free version first to test compatibility with your device.

Ratings and reviews

I was running the free version of this, but found I wanted to change some of the settings so I purchased the full version. There was a bug with the current settings showing correctly. The developer had this fixed within 12 hours.

Love it.

A decent and honest developer offering exactly what it says on the tin, unlike many of the other fractal and similar based cons on the play store. Very happy to support someones work when they show decency and good practice in how they operate and let the work speak for itself instead of forcing payments at me. Thank you.

What's new
