Jin8 seems to be a big fan of Hatris (for real), he's blogging about new Hatris achievements quite frequently. That analysis of his is obviously something he has been working on for quite a while, and now he's using april 1st as an excuse to post it.
wow, a hatris fan... i remember two years ago i blanked tetrisconcept.com and put in just plain text that ttc was shutting us down, and i photoshopped a letter from their lawyers, and then apparently a bunch of 2ch guys thought it was for real.
Well, I didn't mean it like that. But april 1st is a good opportunity to post something like that.. he replaced his entire Tetris site with Hatris related contet rather than just linking to a new page (which he'll do tomorrow when he change it back). It gives you some attention, just like google have used April 1st to release new services in the past (gmail was released on April 1st - "hah.. 1 gig free mail.. good one google! .. oh, it's real?"). In that sense it's a good excuse to do something radical.
