“CYCLORAMIC Just when you think that nobody could possibly have another fresh idea for a phone app, Cycloramic ($1) makes 360-degree panoramic videos — without a tripod or swivel.
You stand the phone upright and tap the Go button. Incredibly, the phone, balancing on its end, begins to rotate itself. Freakiest darned thing you ever saw. Great for winning bar bets or establishing new religions.
If you’ve ever seen a phone scoot itself along a table when it is in buzz mode, you get the principle. The app triggers the phone’s vibration module at exactly the right frequencies to make the phone turn on the table. The phone’s sensors figure out how far it’s rotated.
It works only on shiny surfaces like glass, polished granite or laminated wood (like desks), and only the iPhone 5 has exactly the right balance. It’s a jaw-dropper.”
