Can anyone identify this project for me ? Answered

Hey there. I'm wondering whether someone remembers a project someone made and can link me to it. 

Someone had put small, passport photo sized pictures of their friends in a grid and mounted them on a wall frame. It looked like a guess who set I suppose. Anyway, it was a way of alerting him or her when friends came online. Their light went on when they were online. It was a great project and I want to something similar. I think the board was hooked up to Adium or something. Can anyone remember ? 

Thanks so much
James
