BoingBoing.net just posted a link to gnomz – a web-based comic authoring tool. Just fill in a web form that lets you pick the backdrop, characters and enter some dialog, and it generates a comic. Sounds lame, but it could actually be a handy way to create graphic representations of narratives or dialogues.
For example, I created a quick (and lame) comic about a professor who is concerned about using a wiki.
I would have linked directly to the “live” version, which is generated on the fly, but their database is being hammered by all of the BoingBoing readers.
