Zen! is an amazing meditation app for Android devices.
Just use it for a few minutes and you will feel like a Buddha monk. Nirvana was never so close!
It uses tree generation, handwriting effects and very light concepts about generative music.
Some technical info (The really interesting thing):
In order to make the PApplet more "Androidable" I modified the processing source code to allow resources being loaded from "res\" (@drawable, @raw, etc.) instead that from assets. Also I modified the method "loadImage" to avoid OutOfMemory problems when working with extra hight dpi devices, and when loading large images. Those changes broke a little bit the processing programming paradigm, but make it better for Android pourposes.
If you are interested I can share those modifications with you.
--- The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.
In the next links i show two musical compositions made using Tissue-Like P-Systems, one of the natural computing models that we use at University of Seville as an alternative way of doing computations, based in living cells.
That compositions also have a graphical representation made with Processing, what is generated in real time using musical data; the P-System's output.
This is my first project using processing, i hope you forgive my errors, i'll try to improve my works in the future, and i also wish you enjoy the videos. The music and the drawings are generated automatically in a non deterministic way.
