I urge you to visit her website to watch some of the other videos, in particular A is to D what E is to H is excellent and focuses on the overlap of eating and speaking, there are also shades of eucharistian cannibalism.
Whilst "polyrhythmic swim-time in a bath of unspilled feelings" provoked many musing on voice, language, occularcentricism, bio-politics and social control there are two particular videos that may be interesting for anyone on the Sex, Gender, Species course; the "Well This Is Embarrassing" excerpts one and two.
Heather mentioned another artist to me, Erik Bünger. His videos are excellent too. I urge you to watch three particular excepts of his films on his site:
A Lecture On Schizophrenia
The Third Man
The Girl Who Never Was
I think all of these videos/pieces will resonate with the texts on vocalities. Siren themes, Echo and Narcissus themes, vocal subjectivity themes, Technological modulation themes, haunting technology themes, engendering voice themes etc etc.
I know this post has been scatty, I'm simply too excited by these films at present but wanted to share them so they could be watched and thought about over the holiday.
Lastly, I'll bow out with a Bifo quote (although I heard him in a talk say this quote is actually an observation from Rose Goldsen's book, The Show & Tell Machine):
"For the first time in human history there is a generation that has learnt more words and heard more stories from the television machine than from its mother." - FB - PR. pp.36-37.
