Jello is GUI
The new version of the iPhone software added a number of quite useful features (although I’m still waiting for copy & paste). I think the use of animation to indicate that the screen is in “edit mode” is really quite clever. To edit your “home” screen, you tap and hold one of the icons for a couple seconds, and then all of the buttons on the screen start to wiggle. At this point you can drag them around to rearrange them. Pressing the home button freezes them again. It communicates very clearly and, while some may think it too cutesy, fits the iPhone’s personality.
See it wiggle. See it jiggle…
