It's cute and it's fun for about five minutes, it really is. Then you risk getting motion-sickness if you use it for much longer and you see that there's no way you'd ever regularly use this app. It'd be helpful if you could look UP and DOWN, because in a folder with 112 pictures, I had to move up on an incline to view previews of the picture with any degree of a centered perspective. I'm not sure why the developer thinks any user would want to pay more for an app they'll never use except for kicks than a useful Unsanity haxie for $10, or use the $15 as a down-payment on the egregiously expensive (yet admittedly useful) Path Finder.
