is somebody on this list using snd regularly?

i was looking at this image:

according to the file description it is done with snd.

is this hard to do? hard as in: can i do this in a semi automated way to 12 files all about 12-15 mins long? (about 150mb each)

or is there something similar for puredata?

the end result will have to be exported to vector graphics or high resolution image.

cheers
