Hang Around With Wolfgang If you want your day to end on a high note, try tickling the ivories with Wolfgang Amadeus Mozart (you know, the child genius who went on to become one of the worldıs greatest musical composers). Get out your powdered wig and follow Wolfgang back in time for a guided tour of his amazing life. www.geocities.com/Vienna/Strasse/1025/index.html are the keys to tap out for a transport to Austria in the 1700s. Wolfgang himself will introduce you to his family and show you the piano he learned to play. At 4 years old he composed his first piece and at 5 he gave a concert at Salzburg University. The best part is that you get to hear his music through lots of interactive sound files. You'll probably recognize some of the tunes, because they're used in many movies and commercials today. Hey, when you're the king of classical, your music sticks around for a long time. It's a well-orchestrated tour that will make you feel as if you really know the man behind the music. So let your mouse be the conductor's wand and play Mozart for a while. (This site is no longer available.)

Dear Amy: What does encryption mean?--Marilyn, Topeka, Kan.Dear Marilyn: Encryption is a computer program that scrambles data into a secret code. To unscramble the code, the reader must have a "key." So with encryption it is safe to send things like secret e-mail, credit card numbers and financial transactions over the World Wide Web. For a fun example of how encryption works, go to Thunk.com at www.thunk.com and scramble and unscramble messages. Here's a secret message you can try to unscramble: Pffu wfs. Lfd ovpdanu vc fdc! Rzl
