If you are interested in my Thessalonica package, visit the Thessalonica web site.
XWinGreek is mostly deprecated now, as I recommend using Thessalonica for OpenOffice.org for typing polytonic Greek under Linux systems instead. However, you still can find it on its Sourceforge page.
My Greek font packages for LaTeX are now available on CTAN (again, they are mostly deprecated now, as there are much better solutions available).
