Memories! I hid my top 6 and made a 'random friend' thing. It was an image i.e. http://whatever/random-friend.jpg that linked to http://whatever/forward-to-friend. The server served up a random profile picture - and crucially a cookie header that set the friend-id as a cookie that forward-to-friend would use to send you to the corresponding profile. I was _so_ proud of it at the time...
