As many will know, the Sense 3.0 lockscreen provides a very nice and intuitive interface for you to access key apps straight from the lockscreen. It's a great part of the new HTC Sense 3.0 which HTC are very proud of to show off.
A developer has now released a copy of the lockscreen for use on any Android device. If you're really fond of it and like the idea of accessing apps straight from the lockscreen it may be a great lockscreen for you.
However I still recommend WidgetLocker over any lockscreen replacement out at the moment because of how versatile and reliable it is.
