I had these spring rolls at a restraunt, but as you can see the outside was quite different to the 'normal' spring rolls I usually see.  The texture is light and crispy and looks 'stringy (but doesn't taste or feel that way).  I think it was quite interesting and would like to give them a shot but aren't sure what they're called to search for a recipe.   
It's regular roll made with net rice wrapper It's common wrapper in Vietnam.  Here's site when you can see the package and rolls made with it bearnakedfood
