How hard would it be for Apple to create a basic ossiciliscope or spectrograph instead of the now playing screen? Even thought this is pretty much a useless feature, it would be kinda cool to have a basic viz on the ipod. they could implement it like the stars feature, pressing the action button while on the now playing screen to show the viz. Also by pressing the action button again, they could shut off the lcd? When i have the ipod in my pocket and am using the remote i have no use for the lcd being on. Being able to turn it off would be a nice feature.
