Intercellar is a series of free wallpapers designed 'by accident' by Crtomir Just. I mentioned 'accident' because 'the images are the results of errors in particle simulations'. I think they are super stunning and crispy.
Today, I was just browsing on Instagram and I stumbled across this lovely series of wallpapers made by our pal Jordan Metcalf, a graphic designer based in Portland, Oregon. Focusing his work into lettering and identity design, he designed 3 wallpapers available for your Desktop and Mobile. Initiated in collaboration with 21wallpaper, the one I would totally get would be the design that says: "Put your phone down. Do some work.". Check it out!
