My 2-year-old loves this CD, and I enjoy playing with it, too. You can have it read, or you can explore it - and even I have trouble finding all the 'easter eggs' that do something. There is a scene for each letter of the alphabet - you can go through, starting at "A", or you can jump right to your favorite letter. It is very much in keeping with the style and character of the Dr. Seuss books. And, the software runs beautifully on old PCs, new PCs, or Macs.There is some serious vocabulary in each scene, too - the authors went to some trouble to make as many words as possible begin with the letter under discussion."Annie, Albert ate my apple!""Alligators have atrocious appetites. Albert, apologize.""Alligators are almost always agreeable, aren't you, Albert.""Absolutely."The music and sound are pleasant, even if you're an adult trying to get something done in the vicinity.
