Three of the most popular event organization applications that Mac users use are iCal, Facebook and Google Calendar. CalendarBar allows you to display events from all of them on your desktop in one convenient drop-down menu.
CalendarBar shows a list of upcoming events in your menubar and automatically syncs with all three applications meaning that your events are dynamically updated. However, you can't manually sync your calendars - you must wait for CalendarBar to do it automatically which may be annoying for some.
You also have to trust it with your login credentials for each calendar, which may raise security concerns for some. You can choose which of your calendars you want to be displayed though and the slick interface integrates with your OS X desktop beautifully.
CalendarBar is a treat for anyone that wants to stay organized in style in OS X.
