Slice of Pi

No, not the movie. This elegant program produces sounds based on the unfolding stream of digits that is Pi (i.e., 3.14159 …). When it first loads in your browser, it recites the sequence in French (“trois, point, un, quatre,” etc.), but there are 20-plus other options, including harpsichord tones and morse code. The program was produced in 1996 as a Java applet by Stephen Braham and Terrance Yu. It is housed on the web page of the Centre for Experimental and Constructive Mathematics at Simon Fraser University in Canada, hence the French-language default. (Be warned that this tool occasionally goes offline.)
