Different size transparent hearts moving in all directions across the screen of your device. We use proprietary particle engine so it gives our apps a special look. The hearts move in all directions not just upward that's why Plastic Valentine live wallpaper looks different. Dark crimson background adds some extreme luxury to the app's design.
