A pretty simple concept, but amazing nonetheless, Kuvva (PC and Mac) is an application that changes you desktop wallpaper each day. Each week the application features a different artist, who provides a set of 7 high res images for use. This week's images are c/o Raymond Lemstra whose artwork resembles robot-like faces, which i find really wonderful.

The Kuvva app interface

I think this is a nifty way of discovering new talent, as well as make your desktop less boring, since there's always some new image to look forward to each day.

Also available is a Kuvva twitter application that changes your twitter background and colour scheme much like the desktop app.
