The slides have been prepared in SVG, and need an SVG player or plugin to view them. You may want to check the SVG Implementations' page for more details on players and on the latest versions. To ensure a proper display of the slides the latest releases of the players should be used.
The first slide is: historyslide.svgz. (If you use older
browsers, you might have problems with the compressed version of the slides; you should then
use historyslide.svg.)
