Zen! is a meditation app for Android devices.
Paint with your fingers and listen to the relaxing music taking the control of your mind while beautiful flowers are being created by a magical experience.
Just use it for a few minutes and you will feel like a buddhist monk. Nirvana was never so close!
Zen! is now Open Source and supposed to be maintained by the community. More info at: www.juankysoriano.com/zen
