[...]Conlusion: lindar is not stupid.
Currently I think that this concept is not related to motion at all. It should be called chirality.If {farna} is just a vector and {klama} is a movement according to such vector then"chirality" is a twisted vector and {carna} is a movement according to such vector.
chirality (uncountable)
Sorry for such term as "twisted vector" but I'm not an expert in such things.If there are mathematicians or topologists around please enlighten us.
