A generative implementation of the famous and amazing THX deep note, where random voices convene on a major chord. I added extra overtones to make it sound like a G.F. Haas piece. With a multi-dimensional oscilloscope to represent the sound in coloured lines. Unique each time you run it! Implemented using WebAudio (actually the first experiment I ever made with WebAudio, a couple of years ago), and animated using the built-in FFT analysis from WebAudio, coupled with HTML Canvas (just did this part yesterday). Because there are a huge number of oscillators + all the FFTs, it's quite heavy...so it sounds prettier on a computer. I'm sure it would be possible to make a much more efficient version but I was more interested in trying out the visualisation this week than optimising the audio code!

Try it a few times! You can also layer multiple renditions on top of one another, as long as the computer can handle it!
