Relativity Widget allows you to visualise Einstein's theories of relativity right on your home screen. Two modes : • Special Relativity: imagine that you are in a spaceship travelling at a chosen speed. If you travel fast enough, time will pass differently on earth... • General Relativity: you are on earth while a friend of yours went on a journey, in a spaceship, at a chosen distance to a Schwarzschild black hole. If you are close enough, time will pass differently in the spaceship... Relativity Widget clocks represent the difference in time flow, since midnight, between a high speed / high gravity experiencing reference frame and a low speed / gravity one, according to Einstein's theory of relativity.

Time isn’t just numbers; it’s a living canvas. Reimagine your desk clock. No ticking, no clutter—just color, motion, and time. The Artclock is a high-concept, kinetic timepiece designed for the modern aesthetic. It moves away from the ticking clock and toward a fluid representation of "the now." Experience a clock that breathes. The Artclock transforms the passage of time into a mesmerizing visual journey of light and color. Inspired by the natural rhythms of the day, The Artclock uses dynamic layering and smooth animations to show you exactly where you stand in the current hour. Watch as the minutes "slice" through a foreground of color, gradually revealing the foundation beneath. As the day turns to night, The Artclock follows the sun, shifting its palette to match the world outside your window. Features You’ll Love: Tailored Transparency: Use the custom glassmorphic slider to adjust the depth and intensity of the clock's layers. Fluid Transitions: Watch the hour reset with a satisfying sweep animation that resets the canvas. Visual Hourly Progress: See the hour pass through a growing circular reveal. Always On: Perfect for use as a dedicated desk clock or nightstand display. Minimalist Customization: Switch between numbers and words, and adjust transparency to match your style.
