@pipipipopopo - wow man, great entry. The H shape that you posted is obviously strong. The animation treatment in the lower right of your second post is simply brilliant, I can picture that so easily, and what you could do with it is endless. Only feedback I could really give you is that I know Keccak has expressed that he would like a logo that it "friendly" and commercially viable, where the aggressiveness of the saw teeth might be leading it away from this direction. But what a great shape to play with.
