Moving Lines: I Ching

Moving Lines is the I Ching, the Book of Changes. CAST WITH LIGHT Hold your iPhone or iPad over a light you choose. Then hold the button and let go, six times: each time you let go, one line is cast, from the bottom up. The line comes from the grain in the camera's frames. Light reaches the sensor as single photons, and no two frames catch quite the same number of them. The frames never leave your device and are let go as soon as the line is cast. THE TEXT All sixty-four hexagrams, with their judgments, images and lines, in three editions: Richard Wilhelm's German of 1924, a new English translation made from it for this app, and the Chinese original of the Zhouyi. Wilhelm's introduction and commentary for each hexagram are here too, in German and in English. Choose the edition in Settings, and browse the Book by its sixty-four figures. READINGS YOU CAN CHECK Seal a question, and the reading comes from your question and the time, hashed with SHA-256. The time is the minute you asked, or the hour or the day if you set that in Settings. The same question at the same time always gives the same reading, so anyone can work it out again. You can also cast in one tap, without a seal. Use the odds of yarrow stalks or of three coins. TODAY'S HEXAGRAM One hexagram a day, the same for everyone on Earth. YOUR JOURNAL Every reading you cast goes into your journal, with your question. Add notes and tags, and search them later. Your journal stays on your device, and Export saves a copy as a file. PRIVACY No account, no ads, no tracking. Your questions never leave your device. ACCESSIBILITY Works with VoiceOver, Dynamic Type and Reduce Motion, in light and dark appearance.
