I facilitate a Prompt Group for the Knoxville Writers' Guild and I like to bring in objects as well as images to stimulate an 8-minute writing frenzy. We all share what we've written afterwards. I use things like a little figurine, a sea shell (nature's art), a net bag of marbles... Tactile senses will stimulate writing, too. I remember simply describing an object I could touch, as well as see, triggered some powerful images. I own a tattered blue cloth wallet. In a few minutes back in August 2010, while at a restaurant, I had immersed myself in the poignancy of loss by simply starting to describe the wallet with no agenda for creating a poem. My character in this narrative poem had lost his Vietnamese wife when Katrina hit. The worked is called "Tattered" and has been published in [i]Poetry Review (Songs of Eretz)[/i].
I said all of that to say this, [i]Visual Verse[/i] is an interesting venue that encourages writes of 50-500 words to a visual prompt, presumably in an hour. These are not masterpieces, but they will likely publish most submissions. I think this can be very encouraging to new (and not so new) writers. I think they are fun, so I occasionally play. Here's my June work to an abstract art: See The New Mathematics.
They just posted the July image, a color photograph, and you can submit your work to it. (And by the way, I sent them a lyrical poem today, too called "Song of the Sun.")
Just check the website in a few days to see if they took it. This is a German based publication, so you can get an international publishing credit to your name :-)
Anyway, just have fun with this! Poetry or Prose.
