This thing is so awesome, I just had to share it.

Enable sound (with headphones or low volume at first :D), and just draw stuff.
The two I found exceptionally cool:
-sine wave, 120Hz, and redraw it be all jaggedy.
The sound of a transformer? I didn't expect it to be so close!
-square wave, maybe 200 Hz, and play around with the duty cycle (change high/low ratio)
The sound of a PC speaker? Old game sounds? It seems they just took a digital signal straight to the speaker!
