Awesome, until I read down to the end:

Maybe the most spectacular results are those achieved by Dr. Masaru Emoto who proved that sound changes the molecular structure of water. Depending on what kind of sound it “hears”, the water structure consciously shows if the sound evokes positive or negative patterns i.e. emotions.

Zuh?

I am a mentor for 4th graders with the Science Club for Girls (http://www.scienceclubforgirls.org/). At the beginning of each session we listen to tracks on this site to get everyone calmed down and focused for the weekly activity. They thought it was silly at first, but now they request it!

Here's a track I generated that should provide interesting results if you use it to fall asleep to at night:

I made "Sitting with Darth Vader in a rowboat that's on fire".

You're really treading on Aphex Twin's turf there.

Needs more lemur

Very creepy indeed.

Those of you of a more "hackable machine" bent may find Boodler (http://boodler.org/) interesting to play with as a soundscape generator. I can't comment on how it compares to this Flash app, since I don't have Flash on this machine; I'd be interested to hear such a comparison from someone who's tried both.

Could use some way of voting/sorting generated tracks. But otherwise awesome.

This is one of those things that struck me as genius before I even hit the link, and thought, "Holy crap, why haven't I made something like this?"

Than I read the text underneath the Flash portion. Maybe that's why.

This is amazing. Thanks.

I wish this had cicadas!

This is incredible.

Simply awesome!
