This is a plot of frequency (X axis) versus time (Y axis) with colors representing intensity (like weather radar). I stuck the picture into Adobe Audition and got a crazy sound file (don't listen too loud!). Click here to open an MP3 file. (It's not really clear what direction Audition is reading the image and I'm too tired tonight to experiment with it, it's still a crazy sound!)
Welcome Boing Boing readers!
Wow, here's the original file from Jamie, it's even cooler than the one I made!
