I don’t understand why Kuvva isn’t more popular. It’s brilliant, simple and free: what more could anybody want?
Each week, Kuvva get an artist to design a series of desktop wallpapers. The free app then changes the desktop wallpaper to a new design each day. Over the course of a week, the wallpapers are all from a single artist, usually in a single style. Then, the following week, it’s a new artist and a new style. Sometimes it’s photography, sometimes it’s digital art, sometimes it’s hand-drawn. It’s a really brilliant idea, and it’s totally free.
Occasionally, the art is bizarre enough for me not to want to display it at work, but there is a function to designate “favourite” artists, and have only their work appearing.
Overall, Kuvva is brilliant, free, and available for Windows and Mac. What are you waiting for?
