You guys with all those icons.
Windows has a decent inbuilt one, all my files are either in the cloud full time or backed up to the teeth, and I try not to use adware/crapware.
I have two icons on my desktop - Recycle Bin (which I have renamed to a " " character so it has no name), and Display Switcher (as I have multiple monitors and a 42" TV connected to the one graphics card).
On my phone now so can't poast a picture, although my background on my desktop is currently a tasteful picture of this lovely young lady
It was Ivanovic last week.
On my Macbook, which I usually use, it's a slideshow of various Federer pics.
On my iPhone 6+, the lock screen is an zoomed-in IRL photograph of Ku-ring-gai Chase
by Sidney Nolan from last time I visited Australia's National Gallery.
For reference I'm 18.
