Add the Wikipedia picture of the day as your Mac display background! First, make sure you have Dropbox installed on your mac. Then, add this Recipe and wait for it to Trigger. After that, the folders will have been set up and the first image been saved. You can then set it as the target wallpaper folder in your Mac Desktop settings. Choose how often you want it to change and voilà!

This Trigger fires whenever a new picture of the day is posted on Wikimedia Commons.

This Action will download a file at a given URL and add it to Dropbox at the path you specify. NOTE: 30 MB file size limit.
