My seven-year-old daughter Jane has been having fun with the Elf Cam iPhone Christmas app. It's got several nifty features, including a compass that, when pointed at the North Pole, will play the sounds of the elves busy at work in the toyshop, and a series of videos called "Ask an Elf?" where a snarky and rather large elf gossips about goings-on at the North Pole.
It also has a feature that allows you to set up your camera on Christmas Eve to record Santa coming out of your fireplace (or walking into room if you don't have a fireplace), so you can show it to your child in order to prove that Santa Claus is real.
The graphics and music are cute, and $1.99, the price is right.
