Thanks to David Bernstein, here's a Facebook retelling of the Jews' Exodus from Egypt. This smart-ass story may even catch the ear of the "wicked" child (who is defined, according to aish.com as " the rebel who wants to succeed in his new life and take on Western values. Although he has grown up in a home full of Jewish values and an integrated Jewish life, he rejects this in favor of integrating into Western society and becoming accepted as the new American.") My favorite entry: Hillel sent you Sandwich.
Of course, if you're old fashioned and want to download more traditional free Seder Haggadah (Haggada? Haggaddah? Hagaddah?) resources, try:
The Digital Haggadah (where you can actually hear the songs chanted)
The Jewish Federation Hagaddah
The Orthodox Chabad Lubbovitch Haggadah
A Cool Illustrated Haggadah called Telling the Story (by Barry and Sierra Polisar)
A Bunch of Other Seder Materials
And should one want to put all of this in the proverbial big picture, one might have a look at some of the titles in "Judaism and Jewish Philosophy: A Selected Bibliography," available at the Ratio Juris blog: http://ratiojuris.blogspot.com/2009/03/judaism-jewish-philosophy-selected.html
