WaveMind: A Ritual-Rich Tool for Self-Fulfilling Prophecies With a gentle swipe, you can accurately convey this message: I have indeed become calm; I can indeed play tennis now. WaveMind doesn't do much—it simply harnesses the power of self-suggestion to tell you to "believe in the power of belief." This was originally created to emulate a project from Black Mirror, but during development, I suddenly realized that rituals like - "Japanese people writing the character '人' (person) on their palm and eating it when nervous," - "rhythmic chest thumping like in The Wolf of Wall Street," - "taking a deep breath before going on stage," and - "the protagonist in Billions snapping a rubber band against himself"... all of these use ritual to achieve self-suggestion, ultimately fulfilling self-made prophecies. These rituals include: - "Slide to adjust values" (yes) - "Clap three times" (no) - "Rhythmic chest thumping three times" (no) - "Take a deep breath and say 'YES' to yourself" (no) - And many more These rituals will be gradually implemented based on future feedback. Main Features: - Create/Delete Projects: Review your projects and adjust them flexibly. - Visualized Values: View the current values of your mental (Mind) and physical (Body) indicators. Note: these values are for reference only and are not backed by actual medical data. - Task Rituals: Adjust values after completing tasks. Currently only supports slide adjustment. Prayer, writing blessings, wishing upon shooting stars... these rituals may not bring immediate change, but we choose to believe. It's this power of belief that, when we eventually achieve our goals, makes us grateful to some ineffable force. But that doesn't matter—what matters is the achievement itself. Multi-Language Support Enjoy WaveMind in multiple languages: English, Simplified Chinese, Japanese, and Spanish. More languages will be supported in the future.
