[PD] looking for video of performance

[Oded Ben-Tal]

A while back (probably more then a year). someone posted link to a nice 
video of performance with a video camera capturing the contours of a 
rubber(?) membrane and using these to generate sounds. I was trying to 
locate these again as an example to show to my students but I couldn't 
find the right set of keywords to find this message through searching. 
does anyone remember that post by any chance or who posted it?

thanks
Oded
