For players (such as Baby Boom) that will be used in a bedroom setting, propose having the default clock transition skins from "day" to "night" using the ambient light sensor.  

1. For dark rooms the clock would dim the contrast on the text to 51-102 RGB and display a night sky wallpaper with subtle stars.  Clock numbers would be rendered to be sitting on a cloud using the existing dropshadows.  Furthermore, the date, day, and month could be hidden if desired.

2. For light rooms clock would remain as is with exception of wallpaper would be revised to have natural lighting environment.   

This proposal could be extended to incorporate weather information for future rev's.
