With "Balloonimals," an iPhone becomes a clown's best friend. This nifty app takes advantage of three of the iPhone's features to create balloon animals like the ones you see clowns make. To make the balloon animals, you start by choosing an animal. Then, you blow into the microphone to inflate virtual balloons (you'll need an external microphone if you have an iPod touch). Once your balloonimal is inflated, you shake your iPhone and the built-in motion sensors do the rest. Shaking your phone twists and turns the balloons into animal shapes. You can make a Tyrannosaurus Rex, a unicorn or one of seven featured balloonimals. From there, you can play with your newly created balloon animals until you're ready to pop them. That's right, with a touch of the screen, you can pop your balloons.
Perhaps the one drawback is lasting appeal. Kids may burn through this app relatively quickly as once you create the seven available balloon animals (only the T-Rex is available in the free lite version), you're done. You have nothing new to play with. Also keep in mind that since you shake your iPhone or iPod touch to shape your animals, that in itself could pose a danger to your device if your young one drops it.
