Cycloramic is cool app to make your iPhone 5 dance and do a 360 degree spin. It doesn't just spin but takes a panorama shot of the surrounding. Doesn't it sound cool. The app is currently only available on the Apple app store. A couple of disappointment with Cycloramic is that the app is compatible only with the iPhone 5 and is a paid app.
Keep your iPhone 5 upright and on a level surface for the phone to do a spin. Activate the vibration option (Go to Settings - Sounds - Vibrate).
