A Developer called abell413, has already ported one of awesome lockscreens, the Android L lockscreen (download here). Now he ported a lockscreen from one of the most powerful and most discussed devices on the market available, the OnePlus One!
The lockscreen looks and feels the same just as it is in CyanogenMod 11S. You can customize the colors, and it's very intuitive, too! By default it shows you the current date & time, battery life and notifications. It also has its interface when listening to music. You can also access the camera by swyping to the left.
App is free & available on Google Play Store!
