The source code was already available for Qt developers, but for those wanting to test it out on Nokia N9 or N950, go to "the Nokia store":http://store.nokia.com/content/290296
and install it directly on your device without compiling.
Please rate / comment on it on the store.
I'm open for your suggestions / possible use cases. If you post your comments here, you will have more space to elaborate compared to the available space on the store.
I will vote up and install it!
Neat! Nice one.
