Cool Postcards – Travel Postcard - Send Vacation Postcards! Review

Pulls pictures in based on your geolocation and mashes them up with your own pictures. That's cool. But even better, it seems to know what time of year it is, so autumn in NYC means that it pulls great fall pictures of the city and combines them. It also seems to know whether your pictures are buildings/sites or restaurants or landscapes and oddly matches them.
