You can read Pope Benedict XVI's Easter Greeting in many different languages on the Urbi et Orbi ("To the City and World") page at the Official Vatican website. The 2009 message in Latin is "Resurrectio Domini, spes nostra," which is translated, "The Resurrection of our Lord, our hope."
The Vatican's Liturgical Calendar page has a selection of Easter Music, much of it in Latin, which you can enjoy. You'll also find links to past Holy Weeks, along with the Easter Greetings from past years.
Today's Albany Times-Union (New York) has a wonderful feature entitled Enduring Symbol (April 12, 2009) about the different types of Christian crosses. In this article, you can read about the different types of crosses and view some very lovely images. On some of the crosses, you'll see IHS, which are taken from the first three letters of the name of Jesus (Ιηςυσ) in Greek. Other crosses include the Chi Ro, (X Ρ) which are the first two letters of Christ (Χριςτοσ), also from the Greek alphabet.
