Nook Screensaver set: Piranesi - Carceri d'Invenzione

A nice feature of Nook (and, indeed, of many other ebook readers) is the possibility of using custom screensaver.
Actually, there would be no need for using a screensaver on an eInk display (on the other end, they also don't have almost any side effect, even on battery life); so its only function is just to let you enjoy nice pictures!

I created a screensaver set collecting the famous and beautiful series of (16) prints The Prisons ("Carceri d'Invenzione") by the Italian artist Giovanni Battista Piranesi; the images are converted and optimized for usage on Nook (and any other eInk reader with display size of 800x600 px).
Some samples of the image set:


You can download the entire set here.

The installation on Nook is pretty simple and could be done on any (either stock or root) firmware version. Simply unzip the archive and copy the folder containing the 16 images into folder "my screensaver" of the internal SD drive of Nook (of course, after connecting the Nook to a PC through USB). Then config this screensaver on Nook clicking, starting from Home screen: Settings -> Display -> Screensaver -> "Piranesi - Carceri d'Invenzione".
