A cool-ish background for the first Testitapahtuma-event.
Includes some audio-visualization components. Requires Virtual Audio Cable or a Stereo Mix device to work.
Of course you can change the logic in picking the audio device to overcome this limitation and use something else.
Configuration is static in the canvas.js file and partially documented.
Running It
Run the simple web server to serve the files with node server. Then allow the insecure page to access the microphone in your browser's settings for the specific page. This is often required for insecure origins.
