Wow. Very cool. It's actually better than Tk for my use – I don't have to boot up X windows. Too bad it's not quite as sophisicated but then again, im not good enough to make use of even 5% of Tk so CamelBones will suit me just fine ::grins::
Not quite as sophisticated? Think not. :) You also have full access to the Interface Builder to lay out your interface. So far I've found it both easier and more powerful than Tk to use for building GUI interfaces.
