Have not played with it too much yet but it will for sure be used in some form or another. There is some videos that will show all the functions nicely. What will be mentioned however is that this is based on a small electronic device/jewelry that Mr Nightradio made about a year ago and here is a nice article from Palmsounds that talks about how Mr Nightradio is pushing the boundaries in mobile gear both virtual and tangible:
Yes Mr Nightradio always forward pushing boundaries!
There is a free version for Windows/Linux/Mac here (slightly limiting as there is not the same freedom to use the camera and use of the mobile microphone):
Google Play info:
Quantum VJ HD is a simple glitch-style audio visualizer (video generator). It can receive sound from the microphone or from the Line-in port (depends on the system settings). Sound will be converted to the graphic elements byte by byte. The final video can be mixed with the camera stream in real time.
The app is also available for Windows, Linux, OS X and iOS.[ Multitouch control ]
