HD Greetings has taken e-greeting cards to a whole new level. You can send cards with 3D and stop motion animation rather than the typical two dimensional flash animation card. And that's just the beginning. You can add photos, text, music, and there is the function of adding voice clips coming soon. The use of sharing widget makes it easy for you to email, post and embed your cards.
They call this HDGreetings but it is not really High-Definition. I still thought that this was a cool service and so thought I would share with you all.
