Here are some ice cream mountains to cool you off on what is usually the warmest month of the year at least on the Northern Hemisphere ;)
There are two versions of the smartphone background. Anyone who owns an iPhone knows that it's almost impossible to get it to switch to the dark font on the lock screen unless the background is completely white. Otherwise you get a gray overlay that dulls the colors. Thus the white and black version, like night and day!
As usual the desktop calendar and smartphone background are free for personal use. Click on the images below for the full size. Then right-click and select ‘set as desktop background’. Enjoy!
