I like the Kindle Fire HD's screensavers. All are details of culture and media, and all are pleasant and artful.
There's only about a dozen though, if it were me I'd have put in over 50. It's not hard for a good photographer to make such pictures, and it's a good thing if the customer does not get tired of the same pics. Many people got very tired of the drawings of old authors on the early Kindles.
They also ought to make it easy to put in your own pictures, I haven't yet seen a setting for this.
