On Saturday I brought the Soundplane prototype over to Robotspeak in San Francisco's Lower Haight, where there was a really great and attentive crowd. We played with the Soundplane and Max/MSP, and the alpha version of Aalto for Soundplane. Here's part of the introduction taped by Jack Hertz:

I also brought some copper foil tape and with my laptop's built-in audio interface, made a simple capacitive distance sensor showing the basic principle the Soundplane is built on. I hope this demo showed some possibilities for exploring DIY sensors. When I get time, I would like to post some more detailed instructions on working with this simple technique.
Thanks all for coming, for asking the good questions, and to Robotspeak for hosting me! It was great to meet some more of my interweb friends in person.
