I actually backed this on Kickstarter and was pretty disappointed. Half of the light strips are now faulty (started only a few months after receiving it) and the software never gets updated. Most people actually end up using Ambibox software instead. You can learn more about it at http://www.reddit.com/r/lightpack
@stephensilber thank you for the feedback! we recently fixed almost all of the major issues, including multi-monitor support. So just grab the latest version of Prismatik app from our website. And we are going to make a major release coming weeks with brand new UI
