Some of these are taken from interfacelift.com – some were found from various posts on reddit.com. I use all of these pictures on rotation. Enjoy them on your desktop by right clicking and choosing “Save As..”
A big thanks to all the original artists who made these images. If you would like a credit, please mail me and I will be happy to add your link and name.
EDIT: I’ve added another nine amazing vector graphic works by artist celsojunior
