Here is what I have done with my lock screen after reading this thread:



I took away the 'swipe to unlock' text and the slider graphic. I then created a script containing wget and ImageMagick commands to download my Last Fm statistics as a transparent png image and overlay the image on the green background. The script then copies the final image to the 'backgrounds' folder of my theme. I use Alarmed to automatically do this once a day. So whenever the phone is locked and I press the power button, I get to see my latest Last Fm statistics.

Why? Because it is possible Maybe a weather forecast or other info downloaded from the net would be more useful
