Facebook mutual friends for three?

[Aleksandar D]

Is there any application on Facebook (or some other way) that can show me mutual friends for two of my FB friends, or even mutual friends for three of us?

There is one but I can't find it
its a ball that connects your friends with strings
The logo is a string ball with rainbow colors with the friends icon of facebook it allows you to view mutual friends of a network, all of your or just hand picked friends.
