Sunrise 2.0 - lets you automatically play sounds or  activates the backlight on your Newton MessagePad every time the device is turned on or off. If you usually use your Newton in dimly lit areas, or want to customize your Newton's sound playing, you  may want this package.  On the other hand, if you don't have a backlight Newton, or are worried about battery life, you can probably live without this package. If you're looking for an easier way to activate your backlight only occasionally, be sure to check out Silk, from Catamount Software, or In The Dark, by Don Louv.  They both also add floating representations of the silkscreen, so you don't have to stand on your head when using your Newton in portrait mode.
