Signal was uploaded on November 4, 2009. It is a video reply to Entry 17. Its description is "again". It is tagged with "marble", "hornets", & "ark". In total, this clip is 0:31 long. Stock footage and audio from an old movie is played. The video has a strange red-blue effect on it and the audio is slightly distorted. The voice of a narrator speaks through the video, saying, "Just wait 'til we're alone together, and I'll show you something new, something [c]old, something sleepy, something of cease and peace, and the long bright curve of space. Banish them, refuse to speak. Leave them. Go upstairs to your room. I will surround your bed. Close the windows, so that none will ever again be able to enter. I will be waiting for you."
