Timed Pause

Hey,

I am wondering if there is any way we could have a
timed pause. What I want to do is to move a picture in
the slide without pausing. So at each step it should
be removed from the current position and displayed in
the new position. I tried to use the following
structure, but it uses pause. 

\newcount\pausecount
\pausecount=0
\def\mypause{
  \ifcase\pausecount
    \pauselevel{=1 :1}\or
    \pauselevel{=2 :2}\or
    \pauselevel{=3 :3}\or
    \pauselevel{=4 :4}\or
    \pauselevel{=5 :5}\or
    \pauselevel{=6 :6}\or
    \pauselevel{=7 :7}\or
    \pauselevel{=8 :8}\or
    \pauselevel{=-1}
    \else\relax
  \fi\pause\advance\pausecount1\relax}
\multiinclude[pause=\mypause,graphics={angle=270}]{pic}

What I am looking for is to use a timed pause, like 

  \fi\pause{0.5}\advance\pausecount1\relax}

so that it doesn't wait for an input, but at the same
time, increases the pauselevel.

Any help is greatly appreciated.

Vahid
