The video you're querying about is a Japanese porno from the company Soft on Demand (SOD) as the content is censored.

It's not an experiment, you could say it's art I suppose but in all honesty, it's just a flat out Japanese porno. I wish there was a lot more of this stuff.

The only problem I had with this video (besides being censored) is related to your tongue in cheek comment about this being sexual faccism. All the participants have sex in the same position and cvhange at the same time. It'd be great to see 500 people screwing just the way they wanted and perhaps switch partners every so often.

But all in all, this is a great video, very different, very interesting.
