This is a curiosity. The goal of FTOSX is to create a seamless
blend of the Linux kernel with binary support for Mac OS 7/8,
Windows, and SCO on top of the ReiserFS filesystem, and building a
suite of apps from an amalgam of the best of KDE (a hacked version
is available from the site), GNOME, and OpenMotif. Steps are
included for creating your own FTOSX installation, though the
timeline (which ostensibly explains when this all comes together in
a seamless whole) is 404ing at the moment.
