So basically this app is meant to amaze you. If you tilt around the center of the screen, it will give off a 3D holographic effect. You can also see the effect if you look straight down the screen of your device.
Another cool thing of this app is that it changes color. It will start blue and then slowly change to green and purple.
Overall Ballerina is an excellent app to entertain people and very pleasing to your eye. It’s currently $0.99.
