Here's Toetag. Another example of portability. :)

Here's "Toetag." It's an open source Quake level editor being ported by Eric W.

As you can see he's been able to make a fair amount of progress in a number of things. The NSStepper/NSStepperCell for instance has been improved as well as Font display among other things.

Here's the original website here.

More to come... :)
