Reminds me of the Primer from Neal Stephenson's A Diamond Age. Passage from Nell's first experience with the Primer:<p>The book spoke in a lovely contralto, with an accent like the very finest Vickys. The voice was like a real person's- though not like anyone Nell had ever met. It rose and fell like slow surf on a warm beach, and when Nell closed her eyes, it swept her out into an ocean of feelings.<p>"Once upon a time there was a little Princess named Nell who was imprisoned in a tall dark castle on an island in the middle of a great sea, with a little boy named Harv, who was her friend and protector. She also had four special friends named Dinosaur, Duck, Peter Rabbit, and Purple. Princess Nell and Harv could not leave the Dark Castle, but from time to time a raven would come to visit them..."<p>"What's a raven?" Nell said.<p>The illustration was a colorful painting of the island seen from up in the sky. The island rotated downward and out of the picture, becoming a view toward the ocean horizon. In the middle was a black dot. The picture zoomed in on the black dot, and it turned out to be a bird. Big letters appeared beneath. "R A V E N," the book said. "Raven. Now, say it with me."
