alanback: To clarify a misunderstanding: I care about the name of the game and would like to see it changed. I discussed this right after the game was introduced but Fencer sayed he didn't want to change it. Ok, for me this ends the discussion about the name of the brainking feature.

It doesn't end the discussion about which name is correct. In my post I only wanted to correct a mathematical error (that a sphere and a torus are equivalent), and btw, KotDB has described this perfectly. Last time I was too lazy to type a long explanation.

I hope this is now really my last post on this subject.
