Apple Wireless Keyboard LED - 40X on Flickr - Photo Sharing!
"Ever wonder how the power LED shows through the aluminum of Apple's new wireless keyboard when it's on, but blends into the metal when it's off? Here's how.
This design feature caught my eye as soon as I powered the keyboard up, so I brought it into work the next day and took a picture at 40X magnification using the scope in our lab. A small pattern of what must be laser cut holes allows the light from the LED to shine through, but hides it from view when it's turned off. "
