Recently while browsing Flickr I came across an image from user Shaahin. The image was a Photoshop mockup of what he wants an Apple mail application to look like.
He says: These days every new Macintosh app looks like Mail.app, so I was thinking about a unique logo for the application, to give it a different look. That name is chosen just for fun, it sounds classic.
I really like the look of this, and hope Apple will do something a little different for Mail 3.0 in Leopard.
