HDI show the last x visitors at the users' Profile?

Hello.
Im working on my local Community-Site.
Is there any way to show the last 5,6,7 . . . Users in the Profile, which have visited this Profile?

An Example:

Tom Visits John's Profile. Later Maria visits Johns Profile. She sees that Tom was the last user who has visited John's Profile.
Than John looks at his Profile and sees that Tom and Maria have visited his Profile.

Is there any way to realize this with Drupal. I havent found any modul or hack.
I also played a while with the profile.module. But my php-knowledge is very low!

I would be glad if anyone could help me!
