embroidered calls

I found these embroidered telephone coversations by louisa bufardeci over at NotCot, and i just love them (by the way, i think the initial burst of popularity was unexpected, as it seems her website has been overloaded).

these are the soundwaves from 13 telephone conversations, all one minute long. she also has embroidered portraits of anti-war speeches.

being the nature-lover that i am, i'd love to see a selection of birdcalls visualized in this fashion....
