The Clock (blog.senko.net)

The article describes a “no-numerals” style timekeeping device built as a set of rotating rings that use physical anchors like Earth’s rotation around the Sun and local geography rather than traditional clock markings. Starting from a day/night cycle and expanding inward to show hours, minutes, and seconds (along with DST effects), it later adds an orbit-based outer ring for a stylized calendar. The author concludes that while the design can be made intuitive for potential outsiders (aliens), it still ultimately relies on human concepts like seconds and human-friendly time divisions.
