Google Calendar got 3 new features via labs recently, as mentioned in their 3 new Calendar Labs post from 3/10/2010. The new features are Event Flair, Gentle Reminders and Automatically declining events.

Event Flair lets you assign an icon to events. At-a-glance you can see which events are more important than others, or other things limited only by your mind.  Gentle Reminders pops up less obtrusive reminders of your meetings, Automatically declining events and lets you automatically decline things at times like Vacation, or other times when they would conflict with your schedule.
