Duck

duck, originally known as Yellow Rubber Duck and known as Rubber Ducky in Windows Live Messenger is a user account/display picture included in Windows XP and Windows Live Messenger, licensed from Corbis. It was taken by Lawrence Manning, who also took XP's car user account picture. It depicts a cutout rubber duck on a white background. XP also includes a similar user account picture featuring a rubber frog instead, although it is elusive and it is not known if Manning took it.

Variations
Along with the duck user account picture included in XP, Manning also took several other images featuring the same type of rubber duck. Examples include one featuring a hand holding a rubber duck, one featuring a row of rubber ducks and one where a rubber duck is feeling left out from a crowd of them.
