Me and a friend started a pet project over a year ago called Chimara. It's supposed to be an Interactive Fiction player very similar to Gargoyle, but more easily integrated in other platforms.

It is our goal that it will eventually be the IF player of choice, also on the iLiad. We're not there yet, but I have been busy the last couple of days creating the first version for the iLiad and I'm curious what others have to say about it.
