In response to Jim Zwick's inquiry:  I teach most of my classes in a
multimedia classroom that gives the capability to project images from an
IBM-compatible computer onto a screen.  Thus, I can use the Twain bio on
Twain's World as a filmstrip, other photos as additional audiovisual aids,
the timeline as an outline of Twain's life and career, the Edison movie as
the best audiovisual of all, the ridiculous animations of the jumping frog
and Huck-and-Jim-on-the-raft for comic relief, and electronic text as text
for display and discussion.  In using the electronic text, though, I'm more
likely to copy it out of Twain's World into the Presentations program
(Perfect Office) or Powerpoint (Microsoft Office), either of which displays
it more effectively.  --Jim Leonard
