I mostly use a folder of assorted backgrounds from anime,games,fur,general art for both my tablet and my desktop, the desktop cycles wallpapers every 20 mins so I'm always staring at a new wallpaper.
I'm also in the middle of uploading the folder if anyone wants to choose from what I post, the link will appear when it's done uploading here:
Current wallpaper:
Step right up come on in, feel the buzz in your veins, I'm like an chemical electrical right into your brain and I'm the one who killed the Radio, soon you'll all see
So pay up motherfuckers you belong to "V"
