Apple's chameleonic casings

Today's Apple-rumor-based-on-a-patent-filing is for some sort of computer case with embedded LEDs that can change colors (must...resist...obvious...Hypercolor...reference). They filed for the patent back in February so it's not like we can predict when or if they might introduce a product using the technology
(a new line of iMacs where you can adjust the colors at will?), but among the possiblities mentioned in the patent filing are casings that you users can adjust at will or that can flash different colors to represent different things
(like when you have new email).
