This is an example of an NTL viral, discussed here.
This viral was created at the start of the Big Brother season. It featured the newest pictures of the Big brother house and the housemates. This was created in a way where the pictures could be dropped in and the game released within hours of the pictures being received. The dancing housemates are resized relative to a horizon that is defined for each background picture. When the images were received they each needed a blank movie clip placed on their horizon and some basic resizing before the game could be uploaded. The game concept is an old one, but was deemed suitable to the NTL audience.
