iZoo (Talking wild animals)

Roar! Hoo! Have you wanted to visit a zoo, but not actually GO to a zoo? Just download the iZoo application onto your iPhone, and you can hear animal noises you would find in a zoo anywhere, anytime! This includes sounds and photos of jaguars, polar bears, wolves, raccoons, bald eagles, and more! You can even add your own voices and add pictures to customize them! Itís like a portable zoo!

The iPod users have to buy special headphones with a microphone in order to record their voice.
