I haven't posted a desktop in awhile, but I want this one on my own screens. If you click the link to download the iPad version, you'll probably notice that it's actually a different image. The larger one didn't crop quite right, but I had another that did.
To download and use these, just click on the link below the image and then save it. The Mobile iOS versions are sized to work with the Parallax feature. If you're using an iPhone 6 or older, then you'll need to pinch and drag to set it how you like it. Thanks to John Carey for doing the research.
Also, I just updated the desktop version and it is now compatible with the 5k iMac.
