This is a lot like Google's auto-awesome videos they came out with last year. On New Year's Eve I got a push notification from Google+ on my Android phone that said something like "Happy New Year!" and when I touched it I got a video that showed an auto-curated video of stuff that happened in 2013 based on my videos and pictures that auto-upload to G+. Pretty well done -- I showed it to my family and they were impressed.
After I saw the version they made for me, it let me pick the background music and re-rendered it to match the music I picked.
