To hear the continuous Shepard-Risset glissando play this OGG audio file.
I bring this particular illusion to you because I feel in our current political climate it seems like things are perpetually sliding and getting worse in this manufactured collapse and we're not making any progress. I'd say yes they are. But they're also getting better on many other fronts. I won't make lists of the pros and cons of our extreme times getting more extreme, good and/or bad, but rather I encourage you to embrace the new opportunities, reject the consumer culture, reject the tyranny, find and share alternative solutions, and above all to keep fighting the corrupt corporatocracy.

Since you've got the bizarre Shepard tone Wikipedia page above I encourage you to read it and/or check out this 6 minute BBC documentary on "The Shepard Tone audio illusion".
