Musical greeting cards? Amazon.com has gone one better, and just announced that it has launched a new line of free, video gift cards for the holiday season. Amazon said its new Amazon Video Gift Cards lets users create personalized cards, featuring photos of yourself or of friends and family, directly included in funny videos. The cards--available for winter holidays, birthday, graduation, and more--are an additional option from Amazon to send during the holidays, birthdays, and other occasions. Amazon already had offered a large range of graphical cards to users, but now users can also send funny videos alongside those gift cards. Amazon said users can send up to $2000 with the cards. Amazon is tapping technology from JibJab for the personalized video cards.
