"Falling Leaves" Concept UI for iPhone

Not sure if the user on Vimeo who posted this is THE Woz, but he or she posted this concept user interface for an iPhone menu application that looks very interesting. The video opens with a UI that displays falling media that appear like little square stamps dropping like leaves to a desktop with contacts, photos, videos, etc. on the face of the leaves. The user can apparently pick up one of the pieces, and if it's a video for example, start playing that video in the UI. Also shows a pretty carousel menu and an awesome looking RGB color mixer for customizing the wallpaper I presume. Very nice ideas here, if only for conceptual purposes.
