Understanding the lights on the 2nd gen Shuffle

Got a new 2G shuffle? Do you know what those status lights indicate? Do you know the difference between the green-orange-orange pattern^[1] and the green-orange-green-orange^[2] one? What about a continuous blinking orange light^[3] or red light^[4]? A le now has a nice little su ort article available that explai all the subtleties of the 2nd generation iPod shuffle light patter and what they mean, complete with easy-to-follow dot patter . I'm not sure how useful this will be to readers with color-blindne , but for the rest of us it's a pretty fascinating read.
