I once saw a latex template, which you could use to create a Chat-Like document which has an appearance similar to current mobile chat applications (i.e. iMessage or Whatsapp).
I am of course looking for a static document compiled by latexor pdflatex and not a dynamic chat program.
I remember that I saw something similar done in LaTeX already, but I was not able to find it again.
I can imagine, that this has been done with tikz before.
