So if you thrust it upwardly whilst holding it, and never let go, simply pull it back down quickly, after a few seconds, it would snap a panorama while it rests in your hands since it doesn't use a gyroscope to tell where it stops accelerating. Right?

This means that if you thrust it upward quickly enough, you could pull it back and hold it there while in amongst a crowd, and when the mechanism reaches the predicted time based upon initial acceleration for predicting its apex, then it will take the photo from within the crowd. Seems like it would make more sense to detect DEceleration, as that would facilitate either an upward OR a downward motion, and it wouldn't be reliant on possible bad guesses at when it would stop moving (dependent on environmental influences such as air viscosity, temperature, wind, obstacles in the path, etc).

Cool idea anyhow. I wonder what it would look like to spin it really fast as you toss it.. Neat psychedelic blurring on MOST of the photosphere, but on the axis, it would be less blurred.
