eCards have come a long way. I remember back in the day when an eCard is pretty much just a webpage with a graphic and some custom text. The real fancy ones have animation and some background music.
The web have come a long way, now a days, eCards can be as fancy as personalized videos. I found a service called JibJab that allows you to paste faces into the characters in the video and have the faces sing and dance. I took 5 minutes to crop out a few faces and the site generated a very funny Christmas video eCards. The video itself isn’t all that funny or interesting, but having faces that you know in the video makes a very big difference. I must have watched it 15 times and laugh every time I watch it.
Give it a try, they have a bunch and some premium ones as well.
