Recently, a new 737NG aircraft was delivered with the new SKY interior, which has LED lighting in the cabin. The lighting can be set in different colors and configurations during different flight moments, like boarding, takeoff, cruise, meals, night etc. The control panel is a touch-screen device in the fwd galley. Also the sidewalls and luggage-bins are very different as well as the PSU panels. See the pictures below or download the zip-file on the pictures page of this site.
