When using Beamer/LaTeX, or even PowerPoint, there are some concepts that can be beautifully explained to the audience if we use a short animation, or a video clip. Which is your preferred application and workflow to do such thing?
Speaking about LaTeX, some animated diagrams can be done with TikZ. Beamer and TikZ have been developed by the same author and all TikZ-commands are overlay-aware; for example:
\draw(0,0)--(2,0);
draws a line only in the second step. Incidentally, using TikZ brings a lot of advantages, i.e, fonts are automatically the ones used in the rest of the document and the picture is programmed. More details can be found in http://tex.stackexchange.com/q/102590/13304
A couple of concrete examples are: http://tex.stackexchange.com/q/55806/13304 where a mindmap is revealed step by step and http://tex.stackexchange.com/q/56582/13304 where childs of a tree are revealed step by step.
Finally, I would like to mention smartdiagram (http://www.ctan.org/pkg/smartdiagram) a package able to create simple TikZ diagrams from list of items. Each diagram can be automatically animated with a very user-friendly syntax; for instance:
\smartdiagramanimated[flow diagram]{Build a Program, Set Up, Run, Analyse}
