I would be interested in learning from you how to use an eps file as the background. Would you be willing to post the lines of code that do this for us lesser mortals?
See page 33 of the powerdot docs. \rput[tl](0,0){\includegraphics[width=\slidewidth,height=\slideheight]{myBackground.eps}} See pstricks docs for \rput and graphicx for \includegraphics. Make sure that your background has the proper ratio width vs height (4:3 for paper=screen), otherwise this command will stretch your graphic. -Hendri.
