I use Calibre everyday. It's part of my life.
As long as my computer is On, Calibre keeps running in the background. Keep fetching News articles from 50+ Websites and News Sources. I use Calibre as my RSS aggregator and read all articles on my Kindle Paperwhite.
In calibre there is this cool 3D preview of Book Covers which shows covers of all the books in Calibre Library.
Here is a YouTube video of this
I was just wondering if it is possible to start this 3D preview of Book Covers as a Screensaver? It will only work if your calibre is on in background.
I don't know if it will work with Microsoft Windows but I use Arch Linux BTW and it might work in linux. What are your thoughts on it?
P.S. - It maybe a very stupid idea. But a cool one.
