I hope not! In addition to your work, I've seen that feature in  
another application, one that I like a great deal- Picsel's Picsel  
Browser and Picsel Viewer applications. It's a doc viewer (PDF, MS  
Office) for various mobile platforms.  You mostly control it with  
various gestures- a double tap with a stylus movement in or out while  
holding the second tap down zoom in and out, and the flick acts like  
you describe.

Incidentally, Picsel Viewer and Browser are awesome apps, and easily  
is the best mobile PDF reader around. The bummer is that you can't  
buy it or download a demo- you can only get Picsel OEM with your  
device. They are starting to change this, but they are moving  
glacially on that front. Which is a shame, as Picsel is an awesome  
doc viewer for PDAs and smartphones.
