I have google calendar at work, but I use iCal at home for todos and more importantly, as my alarm to wake me up for work. I used the alarms in iCal to invoke iTunes to play a song of my choice as an alarm every morning. Is there a way to sync these up (in the backgroud) so every time I get home and open my iCal it loads google calendar, and then every time I make a new event from iCal it will update on google calendar, and visa versa?
