A Sandbox for Productivity & Stress Relief
Modern productivity often pushes for rigid, flashing alarms and clinical countdown displays. The Zen Garden Mandala Timer takes a different approach. Inspired by Japanese karesansui dry landscape gardens, this timer represents the slow flow of time through automated, kinetic sand drawings. Watch a virtual metal bead carve intricate geometric curves into the sand bed, bringing focus and calm to your study, work, or meditation sessions.
Tactile Audio-Visual Feedback
This timer implements advanced client-side technologies to deliver a satisfying sensory experience. Clicking the Full Screen icon creates a distraction-free window, fading out controls and leaving only the expanding lines of sand and the glowing paths. As the marble moves, it generates realistic sand-shuffling ASMR audio generated in real-time, responding dynamically to speed and motion.
Synthesized ASMR Sand (Web Audio API)
Rather than looping audio files that cause repetitive brain fatigue, our timer synthesizes sand friction soundwaves using the browser's Web Audio API. When you rake the sand bed yourself using your cursor or touchscreen, the pitch and volume of the sound adjust immediately to your dragging speed, giving an immersive, responsive physical feel.
Five Geometrical Mathematical Paths
Choose from five mathematical patterns configured to complete exactly when your timer ends:
- Spirograph (Hypotrochoid): Creates star-like orbital paths by rolling one circle within another.
- Fibonacci Spiral: Draws a balanced spiral distribution based on the Golden Ratio, reflecting flower seed layouts.
- Rose Rhodonea Curve: A classic sine/cosine loop creating symmetrical flower petals.
- Zen Maze Spiral: An Archimedean spiral starting from the outer boundary and looping tightly to the center.
- Concentric Ripples: Emits perfect concentric rings, simulating ripples in still water.
