The author introduces their latest project, a Cray Wristwatch, a miniature replica of a Cray supercomputer, running on FPGA technology. The project evolved from the original Cray-1 design to a modern Cray J90 core, offering unique insights into the development and changes in Cray supercomputers over the years. The wristwatch displays a real-time, N-body simulation of Jupiter and its moons, showcasing the capabilities of the J90 core. Despite being a scaled-down version, the project is praised for its novelty, complexity, and charming design. While not entirely practical for telling time, the Cray Wristwatch stands as a testament to the author’s passion for computational necromancy.
