Hi all,
I attached an animation of the basics of sampling and synthesizing made for my csound class here in Berlin using pd and its graphic capabilities. It had quite some effect on my students (they normally use Max/MSP) and definetely changed their attitude towards pd ;-)
It only covers the most basic principles of sampling and synthesizing in the digital realm but IMO explains things much clearer and easier to understand than lengthy written explanations. It might look strange as I'm using a 6x10 console font and didn't check it against the standard pd font.
This also could be considered my first contribution to Krzysztof's pd doc project (although it doesn't document pd itself and might be off topic due to its more general nature).
