At Christmas, a good friend gave me a day calendar that has somewhat offbeat sites for each day. Some are long gone - such is the web - some are truly odd. This one is interesting - it’s based on artificial intelligence (I must like it because I have none of my own). Pick a movie, an author or a book, or music and enter it in this site. It will map other works or artists that are similar and you can follow the trail of authors or music, learning of new groups or new books to try. The music one is like a visual verion of Pandora without the music. The books & authors one was fascinating - I put in an author I liked and wham! there was a whole cloud of names, many familiar favorites, and many new ones.
