Flickr Droid, for those of us that like automatically changing wallpapers:

 Just wrote an Android application which allows you to search the Flickr database, with a tag/search string, downloads small thumbnails of the images, and then gives you the freedom to do a number of operations with them. The app can also automatically keep your wallpaper updated, based on your search string.

 Features:

• Easy search and viewing of Flickr images.
• Upload your photos straight from any Android device to your Flickr account.
  
• Automatic wallpaper updater, based on YOUR search criteria.
• Keyword/Tag/Person search.
• Auto-correct spelling.
• Smallest possible bandwidth use.
• Any image can be assigned to your background/contact, shared, or saved.
• Tilt Control - Use the accelerometer to scroll through images.
  

Check it out on the Android Market / Cryket
