Gauche is a bit wierd to understand for the first time..

Lets see what Gauche means in English ! Then may be we can get a better feel of it:

Gauche: Awkward or lacking in social graces; bumbling; Skewed, not plane

So It is basially a rouge in the sense that it neither stays together nor as Anti.!

I know I have not given the diagram.. But i Hope you have the spirit!

Do u mean anything between eclipsed and staggered config is a Gauche config?

Not exactly... I meant that the rouge elements which "exist"

The other conformers are not too stable. So it is the 3rd conformer basically :)

Staggered is most stable conformation and eclipsed is least stable. Like that what is unique about Gauche ?

yes wherever there is a C-C bond u can ask ur teacher to show the ball and stick models jaise 3d models it will give u a clear picture of the conformational,optical ,and other kind of isomerisms...........else i think u can even see it on the net
