Android 4.1 Google Search "Banner"

How many different combinations are there of that top "banner" (or whatever it's called)? I know when I went to Santa Barbara & San Diego it changed to a beach setting which was pretty cool. Also does anyone know when 4.1 Voice Search will implement commands such as "Post status on FaceBook" or "Turn BlueTooth On"? Probably 4.1.3...

On a side-note, can't wait until I get my Galaxy Nexus this Friday!
