I've been a long time subscriber to some of Google's extra calendars they offer via calendar.google.com. A neat part of using their sports calendars is they update the score in real time. I was pretty surprised to look at my watch to see scores (obviously if you have the calendar complication enabled). Neat trick until third party complications are released in OS 2. Just figured I would share.
Obviously this only works if you use Google Calendar. If someone knows of another .ical service that updates game scores in real time I would love to hear a suggestion.
