Dynamic Paint Live Wallpaper lets you indulge your inner artist! Spray and splatter paint onto your home screen, and watch it run down the wall and react to its environment. Paint gathers in creases and runs down smooth surfaces as you watch!
This is not a movie, it has full support for landscape mode and home screen scrolling! Also works as a Daydream on supported devices!
This paid version includes a full settings screen, with lots of options that let you tweak the detail level of the simulation, switch backgrounds, change paint colors, modify how thick the paint is, how it blends on the wall, and more!
