Icons come out of the android. You touch it, drag to the icon you want to launch, and release. Instead of being a lockscreen you now have a functional and minimalistic shortcut interface that responsively reacts when you need it, and otherwise remains hidden & compact so you can instead see the clock and waiting notifications that are more relevant when you're just viewing the screen to see what's happening or what time it is.
This is how I'm using the alpha.
This second image shows how the notification preview widget could work. You choose what types of messages and how much you would want to appear there, with an option to long-press an item to pop open a larger preview of the content (for example with email so you could preview the body). It is scrollable, also.
