%D This is the third environment for typesetting interactive presentations. I used
17
%D this style for a talk on \TEX\ and \JAVASCRIPT\ at \TUG98, mainly because I
18
%D didn't want to use the same style three times. Therefore this is a rather simple,
19
%D silly style.

%D We use a large bodyfont. Combined with the fancy

%D background, this does not leave that much room for text, but
28
%D presentations should use much text anyway.
