Sundial: Living Astro Clock

Stop watching fake clocks. Watch actual solar shadows crawl across a sundial in real time — calculated with the same precision NASA uses. This isn’t a gimmick. It’s the most beautiful astronomical clock ever made for TV. As the sun moves across the sky (using the renowned NOAA/Meeus algorithm), everything reacts. The shadows soften and sharpen with a 60-step penumbra. The light temperature shifts from warm amber to cool blue-grey. The entire scene breathes through sunrise, golden hour, daylight, sunset, and night. It’s part scientific instrument, part living digital art. Features: - Scientifically accurate real-time solar position (azimuth + altitude) - 60-step physically-based penumbra shadows via CustomPainter - Altitude-driven shadow colour temperature - Ambient occlusion contact shadows + volumetric edge highlights - Dynamic day/night palette that actually feels alive - Radial gradient sky that follows the real sun path - Orbiting celestial minute marker - 24-hour time simulation slider (scrub the entire day) - Built exclusively for the big screen — immersive fullscreen, landscape locked - TV-friendly manual location entry Perfect for: - Turning your TV into a hypnotic piece of living art - Replacing soulless digital clocks - Astronomy nerds with good taste - People who want their TV to feel expensive even when it’s "off"
