Virtual

Virtuals are digital beings from another dimension. When one of their plate-sized spaceships crashes on Earth in London the Virtuals escape by uploading themselves onto the internet in a music file track ‘Alien Infiltratration’. As a result of mass downloading those that listened to the track (like young Rich), entered into a trance state that led them out onto the streets. The Doctor was able to delete the Virtuals from the internet server and paste it onto Amy Pond’s phone before sending them home. (DWAM: Sound Bytes)
