[Wien] Very elemental questions...

[Jiri Bursik]

Dear Florent,
the question was not that simple: Gerhard didn't propose having BOTH 
left<-->right exchanged AND up<-->down exchanged. You can really see 
EITHER left<-->right exchange OR up<-->down exchange in the mirror. It's 
the matter of taste. Man is mostly vertical standing in front of the 
mirror, that's probably why he/she tends to prefer automatically think 
about left<-->right exchange. (Or has it more to do with position of 
eyes? Or has it more to do with fixed floor and easier rotation than 
turning upside down?)
Regards, Jiri
