This app is about zoning out. Just touch the screen and watch the ripple effect.Out of ideas on how to entertain a 2 year old? Let them play with this and zone out on the ripples across the default image or add your own. Want to annoy your parents? Keep tapping the screen until they get tired of the constant drip sound and yell at you. Guaranteed to decrease performance if you use it at work...but we wont tell anyone so go for it!!
