Bijin Tokei is a genre of wallpaper that is popular in East Asia. Every minute
the wallpaper changes to a picture of a pretty girl holding an object that
displays the time.

This app will download the pictures for every minute from your chosen site
without caching them but it will check if images already exist in
sdcard/BeautyClock/pic/site/ and the scheme is always aabb.jpg where aa is
the hour and bb is the minute. In this way, you can have the app display any
images that you want.
