Fredrik Knudsen is a virtual streamer from the verdant Pacific northwest of the United States.

He is the producer, writer, narrator, and editor for the Down the Rabbit Hole series of informative videos on YouTube, where he discusses the histories of peculiar and often obscure parts of history and internet culture, including the chess computer Deep Blue, the horrific Mouse Utopia Experiments, and the confounding TempleOS operating system. He can typically be found with a cup of fine tea in hand.
