T C F is the moniker of Norwegian contemporary artist and experimental computer musician Lars Holdhus. His work explores themes of code, cryptography and privacy through the use of visual, sonic, built and written concepts. Often the titles and descriptions of his work are written in cyphertext, the key to which is hidden within the piece itself. His forthcoming release on Liberation Technologies will further this cryptographic theme, consisting of digital and physical content containing the necessary keys to unlock the full meaning of the work.
