Gun barrel sequence video game adaptation of "Quantum of Solace", the gun barrel resembles the one used for "Casino Royale", as the game adapts elements from both films. As with any cultural icon, the gun barrel sequence has inspired numerous parodies and takeoffs since its first appearance in 1962. The sequence has been spoofed in films, sitcoms, cartoons and in advertisements, including: "The Simpsons", "SpongeBob SquarePants", "Family Guy", "Monty Python's Flying Circus", "Logorama", and "Garfield and Friends". WWE wrestler "Cesaro"'s entrance is also similar to that of James Bond gun barrel sequence. In the 1986 horror/comedy film "", the opening credits show Jason
Automatic sequence is a fixed point of φ—that is, if "w" = φ("w")—then "s" = τ("w") is a "k"-automatic sequence. This result is due to Cobham, and it is referred to in the literature as "Cobham's theorem". Conversely, every "k"-automatic sequence is obtainable in this way. Let "k" ≥ 2. The "k-kernel" of the sequence "s"("n") is the set of subsequences In most cases, the "k"-kernel of a sequence is infinite. However, if the "k"-kernel is finite, then the sequence "s"("n") is "k"-automatic. It follows that a "k"-automatic sequence is necessarily a sequence on a finite alphabet. Let "u"("n") be a sequence
