Living Books were a series of CDs you would either play in the computer lab or buy in book fairs or wherever you could get your hands on shareware. They were essentially interactive picture books that would read to you and you could click on stuff in the pictures and see what would happen. They were pretty ingenious because any kid could have fun with them. Even if you already knew how to read, it was fun playing inside the story or making your own fun sentences from the words up top.
They had all sorts of books from the Berenstain Bears to Dr. Seuss, but Stellaluna was my favorite. They tried to keep with the realistic style of the books, which was a massive undertaking. By far the best looking CD out of all of them. It also taught me real things about bats, like how they are not blind and how a lot of them eat fruit. It was a real misconception-buster for me.
