The Memory Wall is part of the Big Brother House. It consists of all the current houseguests' names and pictures (also called Mangatars). Below each picture is a slot containing the houseguest's key. When a houseguest is evicted, the picture changes to black and white. During the first two seasons, the key is taken away and replaced with a lock once a houseguest is evicted; however, this was discontinued in later seasons.
The Memory Wall appears in the main page of the Big Brother Wiki site while the season is on going as well as the season page. It shows the status of each houseguest such as the Head of Household, nominees, Power of Veto holder, evictees, etc.
The Picture or Mangatar Edit is a minor twist in the Big Brother ORG. As the name implies, it involves editing or changing the images of a houseguest or houseguests on the Memory Wall. This twist is intended to be annoying or comical and does not affect the game.
In Big Brother 1, mustaches were added to the mangatars of all the houseguests on the Memory Wall as one of the antics caused by NotJerby.
In Big Brother 2, there were two instances of Picture Edits as a result of buttons pressed on the Control Panel. One was Boo who got a purple hair and the other was Tommy whose mangatar was pixelated.
In Big Brother 5, Emma's mangatar got a makeover after she chose one of the drinks Yap served in his bar.
