This is a neat interface for zooming in Touchwiz 4.0:

Notice that you hold two fingers on the display, then move it towards you, or away from you to zoom. I quite like this form of gesturing, and can see some novel implementations using it.

In general, I would like to see browsers implement an option for two finger scrolling/zooming, and one finger mouse pointer movement. In this way, it can operate almost identically to current desktop-browsers.
