iPhone 4 gyroscope adds extra dimension to killing games

The iPhone 4's new internal gyroscope not only measures acceleration or deceleration, but tracks orientation. That's going to make games a lot more fun, and here's one of the first, Gun Range. As you can see in the video above, you can spin yourself or your hands around 180 degrees, picking off moving targets as you go.

At first glance, this 99-cent game looks similar to games that have been available for years, but there is this eerie extra feeling along with it, tracking where you're moving. It's an odd sensation, and a bit difficult to get used to at first. This is only the first attempt at employing this futuristic hardware. Just imagine the possibilities with this gyroscope. Mind-boggling.
