Anakin and I are working on a quick OSX util to update our iMoods from the taskbar. You can see a fairly updated visual of my mood on the left side toolbar.
Update: I just finished working on the back-end of this program (ie, command line version) which I think is the easy part so it could still be a few days/weeks off before it will be released. We also need to talk to the folks at imood.com about licensing and distributing.
