Particle Effect - Interactive Live Wallpaper is a live wallpaper application for Android devices, developed by a company called E.A.T.E.L. for the purpose of making users' phones more attractive. 

This application is designed to give users the feeling that they are in the middle of a cosmic space, surrounded by mysterious particles that are constantly flowing and interacting with each other.

The main goal of the application is to make users' phones look more attractive. To achieve this, the developers have used a combination of different live wallpapers, including a background with stars, a galaxy background, as well as a background with space and other various particles.
