Fractals are always mind-blowing. One could regard fractals as a series of ordered frequencies. This project is an experiment trying to explore the rules within, and to present it with sound, which is another incarnation of frequencies.
I used a traditional way to generate the Sierpinski Triangle: Firstly, randomly pick a dot A inside the original triangle, then mark the midpoint between A and a randomly picked vertex, as B. Next mark out the midpoint between B and another ramdomly picked vertex, as C. We let the computer repeat this operation every 2 milliseconds, wait until more than 1 minute and one could see a clear Sierpinski Triangle is formed.
So I made this patch in Max/MSP to achieve the above sequence, and transported every step's coordinate (as MIDI signal) into Pure Data to make a corresponding sequence of sound.

The following sound track is entirely generated by the signals from Sierpinski Triangle using GM Bank only.

The main patch
And here's some alternations of it, by slightly changing the equation in the main patch.
