Wall of members

Hi there,

I am looking for a plugin to build a “wall of members”. Here is an example: http://www.thehappystartupschool.com/happifesto

Members would click on a button “add yourself to the wall”, it opens a pop in / pop up where you can choose to sign in with their Facebook / Linkedin / Twitter account. And then it´s done, their picture would be added on the list!

Thanks for your help.

Thomas
