Art is always one of the best sources of inspiration for designers.
Holly Maguire creates some lovely illustrations, you can see more on Cargo Collective.
An experiment by Xavier Antin, printing a book using a printing chain made of four desktop printers using four different colors and technologies dated from 1880 to 1976. The result is pretty much what you would expect, still a funny idea though.
Wonderful artworks by Lucas Simões, via Today & Tomorrow.
