It doesn't work on my B2 with #537.
Signal and spectrum modes are OK, but systrem is freezing by sonogram
mode. When I interrupt with alt+., I can control system again and graph
is drawn.

This movie is very interesting. I think SpectrumAnalyzer can do almost
same thing if it works fine.
Drawing audio-frequency graph requires realtime processing, so I think
it's difficult to make it with Etoys.
World-Stethoscope morph is designed for kids experiments with
pre-processed sound.
