I've seen them before, but can't seem to find them now.. those tails that animate your avatar when someone interacts with them, like if someone yanks the tail the avatar falls.. whoever makes 'em needs some advertising, cause I've been searching everywhere... and I want one!
Googling for reviews of second life tails only gets me info on "The Long Tail" or on getting "tail"... and searching for interactive tails in-world brings up every tail with interaction, even if it's just chat..
