An highly customizable and interactive live wallpaper based on the app "Force Fields" (you can find it in the "other apps" section).Particles and force fields interact with each other in this cool physics simulation of a gravity system, right on your device homescreen!This is now available for FREE, don’t miss it!—There are many customizations available:- interactive mode;- extended screen: particles can move beyond the screen borders;- background image;- shape and color of the force fields;- duration of the temporary force fields on the screen;- number of particles in the simulation;- interaction between the particles (attraction, repulsion or none) and its strength;- length of the trace that the particles leave when they’re moving around on the screen;- color of the particles and their traces.There are two interaction modes:- you can enable the main force field that will stay on the screen, tapping anywhere will move it to the new position;- if the main force field is not enabled, tapping on the screen will create a temporary force field that will disappear after a few seconds.Finally, dropping an icon on the screen will temporarily attract the particles like a force field!
