The code in 
http://graphics.openoffice.org/source/browse/graphics/slideshow/source/engine/transitions/randomwipe.cxx

to shuffle the squares for a 'dissolve' wipe is poor.  When watching the
desolve, it is easy to see a raster-scan which some randomness is over-layed on.
A better approach would be:
  for (i=0; i< nElements; i++) {
     j = getRandomOrdinal(nElements-i)
     // swap m_positions[i], m_positions[j]
  }

that would ensure every element had and equal chance of being swapped.
