I released a Live Wallpaper named Mad Marbles, it features a nice glass ball effect. Here's a screenshot:
It's my first android app and I tried to do the best I can, feedback and suggestions are welcome!
Marbles move in realtime and distort the background image as real glass spheres would.
Marbles are interactive (they collide and you can select and move them with your finger) and the wallpaper is highly customizable.
Settings include a gyroscope mode... when enabled marbles move accordingly to your device orientation.
Here's the link to free and paid versions on google play:
Hope you like it!
