I fell in love with Google's Earth View from Google Maps Chrome plugin which displays a beautiful place on earth every time you open a new tab. Everytime I opened a tab, I was in awe (which admittedly did stunt productivity a little). I wanted these photos for some sweet wallpapers. After a quick dip into the source, the plugin has a list of ID's and an endpoint which provides the image so I created a script to download each of these ID's to a folder.
$ git clone https://github.com/adriancooney/prettyearth-wallpapers.git
$ cd prettyearth-wallpapers
$ npm install
$ OUTPUT_FOLDER="/Users/Me/Library/Whatever" node index.js

Congratulations, you own the earth. Download complete to /Users/Me/Library/Whatever.
Once the download is complete, jump into system preferences and add the folder (tip: use CMD+Alt+G to type the path) then fiddle with the display preferences. Now you have beautiful, rotating desktop wallpapers (not that you ever see the desktop too often).
