Ambilight like experience using a normal Android device and the Philips Hue system. Needs a rooted device.
This is should be considered as a "works-for-me proof of concept". It runs stable on my device and the effect is not perfect but I enjoy it very much. Again: I coded this app for me and it works here with my setup. If it does not run on yours, you can drop me a note and if it is easy to fix, I will do my best to do so. But I am not a professional, so please be patient and nice.
If you think you can do anything to improve the app, specifically:
please feel free to do so. I would be extremely happy to work together with others. Of course, as this app is GPL3, you are also welcome to fork it and use it as a seed for your own project, as long as it remains open source ;-)
