I've been pretty happy the the recently developed powerdot in
combination with the cool pstricks.  Generally I displace down the page and then
can place objects anywhere I want using:

% atat % section start
\vspace{8.6cm}\hspace{0cm}% start at lower left point
% \psgrid(0,0)(-20,-20)(20,20)%
%
\rput[tl]{0}(1.65,8.0){% across down, inches
\parbox[t][3.0cm][t]{3.0cm}{% \parbox[c][\height][t]{\width}%
{\rotatebox{90}{\scalebox{0.6}{\includegraphics*{slidesfigs/ecorI.eps}}}}
}%
}%
%
\rput[tl]{0}(2.0,8.5){% across down, inches
\parbox[t][3.0cm][t]{10.0cm}{% \parbox[c][\height][t]{\width}%
{\par
\vspace{11pt}\hspace{4.5cm}
{\large\textbf{Information \emph{versus} Energy}
}%
}%
}%
}%
\end{wideslide}

So the vspace sets us to the lower left corner.  The coordinate system
can be seen by unearthing psgrid.  Then the two rputs place objects
where I want on the grid.  Text goes inside parboxes (or in this case
also a graphic).

In powerdot one can pause or set parts to appear at different times.

My slides done this way from my talk at the recent meeting
Perspectives in High Dimensions are at:

http://www.case.edu/artsci/math/mwmeckes/perspectivesInHighDimensions/slides.htm
http://www.case.edu/artsci/math/mwmeckes/perspectivesInHighDimensions/schneider.pdf

The example above is slide 15.

Probably not.
