Yes, of course: download the version of FocusTrack you need (Mac OS X or Windows) from the downloads page. When you're asked for a name and registration code enter 'Demo' and 'Demo'. This will let you try FocusTrack, with a few features disabled, for fourteen days.
If you prefer, you can download a version of FocusTrack with a real ‘mini-show’ in it - highlights from the 2008 UK tour of Equus - to give you something to play with. You can find it here.
