I really like the examples
here (though a URL isn’t provided for the first screenshot.) From that page we see
this which is drawing in data from a Google Calendar but obviously, like in the example screenshot, styling it as needed.
You can see the XML parsed from Google Calendar
here, but he doesn’t list the php code to parse it. Also, the JavaScript code is
here.
A lot of my clients use Google Calendar and would love for select calendars to appear on their sites displayed in a manner other than the standard grid calendar views.
