Please note, that Tetrisconcept.com opened up a Tetris-wiki, that is totally devoted to everything related to Tetris. Their mission is quite cool they say: “Our goal is to compile every Tetris detail known to mankind.”
This project is a must for everyone who wants to go into puzzle-arcade games in general or the mystical world of Tetris in special. There are many interesting details, for example the rotation system of the different game systems or different hints for gaming techniques at certain problems of the game. To get an idea, sneak into the page of the I-Spin problem.

They collect also wisdom and curiosities about Tetris, so why not add your project, if it is worth to mention? In that sense, have fun with that video from YMCK:
