Haven't checked this out yet (it's still downloading on the desktop next door!) But it looks like a means of producing large-format family tree wallcharts (if you have access to a plotter, which as it happens I do!) Will report back when I've experimented.
But if you want to try it out too, this is the download link
UPDATE....have just installed and the programme will "expire" on 15th June 2008 (after which you have to purchase) Time to give it a whirl though!
