Santa Gizmo is a neat little application that lets you track the presents you’re getting people. You can also check them off as being purchased, wrapped and sent. Santa Gizmo also uses smart lists (very similar to smart playlists in iTunes) to break down which gifts have been bought, sent, wrapped, still need to be wrapped and shipped or need to ship.
While the application only becomes useful once a year, for $15 it’s a neat little application if you like to be organized and track how much you spend each year on Christmas gifts. I am sure you could repurpose it and use to track any sort of gift giving event (birthdays, weddings, etc…).
You can grab a copy from the MacMage.com website, and they will donate $5 to the Save the Children foundation. Cool!
