A web site builder/CMS type application using Guildenstern and sqliteral. I'm still in fairly early stages, as i'm building the smaller features, and the "framework" level features necessary, so i can test out some of the higher level ideas for the application, to see what ends up working out. A predecessor with a different UX approach already got scrapped. There's still some open questions with the current approach. :)
I fully expect it to be FOSS, so when i get to a certain point i will announce it here, and people can check it out.
