Lucid automatically starts when you put your device in the dock or when you charge it. The app is very customizable and comes with a lot of functionallity, like:

... missed calls
... next alarm
... many more information from most DashClock extensions

Slideshow view: start a slideshow with images from your device
On Android 4.2+ you need to enable the "DayDream" in the Android display settings to use & configure the app! Note that the system won't start the daydream if you're display is kept awake! Make sure to disable the "Keep awake while charging" option in the Android developer settings (if you have enabled that before). On Samsung devices, make sure to disable the "keep display on while eye contact is detected" option (or how they call that)
You can use the identifiers here http://developer.android.com/reference/java/text/SimpleDateFormat.html to change the time and date format
