This is cool and illegal. What makes me envy of the West (or countries other than Japan in general) is that this kind of attempt is somewhat condoned and praised, while in Japan there would be a vocal outcry and finger-pointing campaign (with some media exposure) to the point where the author would be forced to shut down the project. It's a blessing that people can pursue things like this, and it's a huge shame that Japan is such an anal when it comes to a marginally illegal activity in an open space. (I'm sure some people do it underground though.)
