I'm building a beautiful time zone selector, as a jQuery UI widget.
What I need is a layered PSD file where the bottom layer is a simple mercator world map, and each layer above it is a shape covering the geography affected by each time zone.
I've seen UI components like it, for example the Date & Time preferences in Mac iOS Lion. In fact what I'm building is inspired by that one, but it will be slightly awesomer.
The goal is to lay the map on the page, then as you interact with the UI will highlight the map using a sprited overlay.
I'll resize the images into multiple sizes, so a high-rez original would be awesome.
Sounds simple. But so far I've had trouble finding good source images.
