Check this out! An ultrasound imaging of Joshua Gardner playing clarinet!
During Ultrafest, Thomas Hueber and Aude Noiray recorded Joshua Gardner playing clarinet. They used the Terason-ultraspeech system. A short video that can be downloaded is available at http://hueber.thomas.free.fr/public/joshua_ultrafest.mov
Note that it was more difficult to obtain a decent image quality when Joshua was playing the clarinet than when he was speaking.
