Excellent website which has an online modernized version of Everyman.
A page on Everyman at Goucher College
http://faculty.goucher.edu/eng211/Everyman.html
A good summation of some key information about Everyman, including some excellent suggestions for further research on the play (better, I would suggest, for college students than younger ones).
EveryMan with Lego (via YouTube)
http://www.youtube.com/watch?v=vM5Zwd427iU
A funny, irreverent re-telling of the morality play using Lego characters. Good for reminding yourself of the key points of the plot - but not a faithful telling of all the detail of the play!
