Recently I took my son to a first birthday party where they put up a tv that played a musical snapshow made from digital pictures of their child's first year. The video had a storyline showing the baby grow up from a newborn to the first tooth, first smile, first crawl etc and everything was beautifully choreographed to music with special effects and a personalized Happy Birthday song!
They had got it done from smilingsnaps and it was so touching- I had never seen anything like that before!! I am planning to do something similar for my kid's upcoming birthday- not only will it be fun in the party, but the DVD will be a permanent keepsake which my son would love to see when he grows up! Hope this helps.
