I can see any number of collaborative permutations: one could try to translate a poem into a picture. Or, conversely, ask a poet friend to write something on the basis of a photographic image. There seem to be endless creative possibilities.

In fact, these kinds of collaborations -between artists of different media, that is - were quite common in the late 19th and early 20th century. It seems that quite a few classical music pieces were inspired by paintings.

It would be interesting to have two people - a writer and a photographer, for example- take a trip together and then have them produce a kind of web/photo blog based upon what they saw. I'm sure this has been done already.
