[Tango-artists] Facing direction of icons

[Eugenia Loli-Queru]

Could someone add guidelines regarding the "facing to" of the icons here?

Please note that I am _not_ talking about perspective here, I am talking 
about where the icons should be facing to. For example, these two icons are 
not facing in the same direction and I personally don't like that:

Here is a "live" example of how weird an application can look when its icons 
are not facing at the same direction:

(I am talking about the line-in and mic/guitar icons)

Back in the day BeOS looked uniformed because of its icons had the same 
perspective, but also they were facing at the same direction:

I would love to see the same rule to apply to the Tango icons (just pick 
left or right, I personally prefer left :-). I believe that will make one's 
desktop look more uniform as the brain will recognize them faster because 
the brain will be trained to scan icons in a certain way. If for example you 
have 90 icons facing at the same direction, and 10 on the other, EVEN if 
these 10 icons might be more good-looking than the 90 ones, the user will be 
left with a weird feeling at the end. Simply because his brain would have to 
use  that extra 3 calories of energy to scan them. ;-)

thx,
