Some Yahoo developers have made a RSS feed manipulation tool that implements a dataflow patching environment entirely in-browser. It looks quite similar to Quartz Composer (teh sexy curvy patch cords). I thought I'd send this to the list since it's another visual prog. environment out in the wild, helping people make code visually, which to me is a happy symptom of the continued rise of high-level visual languages and the spread of code literacy. It seems to be under the same blanket TOS as yahoo.com, unfortunately.
