Will Ludwigsen has started writing a story a week on
his blog, based on images that are randomly (or at least arbitrarily) selected, that he then gives himself one hour to write about.
As I write, there are
seven of them. I've read them all and many of them have enough of a creep factor that I believe they would appeal to Pseudopod listeners.
(And in fact, Pseudopod editors might consider buying one or two of them.)
