In wallpaper factory, you can upload your own videos to use for your live wallpaper, or make your own live wallpaper using custom objects that bounce around the screen.  If you've ever wanted to have the faces of your loved ones bouncing around on your phone lockscreen, with a scenic backdrop of your favorite place in the background, this is your go-to app.  You can have as many objects as you want bouncing around in the foreground, and can edit many of their attributes such as:

- Size
- Speed
- Direction
- Color
- Gravity
- And more

Wallpaper Factory also supports transparent images.  It comes with basic cropping implemented, but if you really want to go all out with customization, you can also whip something up in a photo editor and then upload it to the app.  

Have fun customizing :)
