TipCar is a Brazilian car pooling website. Users of the site can offer and find rides quickly and easily.
The home page of TipCar features a cool animated Google Map which features profile pictures and short messages of people looking to share car journeys. The map animates through each message with some nice map rotation and map tilting between messages. You can see the animation effects in the video above.
I'm pretty sure that the site also uses Google Maps to help users find and display car journeys. Unfortunately my Portuguese wasn't adequate enough to navigate to that part of the site.
