%D This is one of the styles I made for the presentation on the \NTS\ project at
%D Euro\TeX\ 1998. You need balls to let \TEX\ typeset graphics, but this style
%D demonstrates that it can be done.
%D
%D This presentation is meant for presentations that build up an idea stepwise.

%D \StartItem We use \TEX\ for typesetting \unknown \StopItem
%D \StartItem mathematical text \unknown \StopItem
%D \StartItem but also for text that has no math \unknown \StopItem

%D We use a lot of color. You can remap them if you want different ones. The ideas
%D circulate over the colors.

%D The rest of the file implements the nasty part: typesetting text embedded in a
%D graphic. The text is collected in a box so that we can reuse it.
