A lock for the ubuntu touch system, as designed by Lucas Romero Di Benedetto. ( http://lucasromerodb.blogspot.be/search?q=unlock )
To test, open Lock.qmlproject in Qt Creator. The Ubuntu SDK is required. ( http://developer.ubuntu.com/get-started/#step-get-toolkit )
You can play around with the colors in colors.js. I've already included two different color schemes. You can also play around with the settings at Lock.qml:43-46 .
For more information, see http://guidopallemans.blogspot.be/2013/09/some-time-ago-i-saw-beautiful-lock.html For further implementation, you will probably need the signal correct on line 36.
