Mathematical π Time Wall Clock with Rainbow Circle ラージ壁時計

This unique wall clock replaces conventional numbers with radians and π, visualizing time as a full circle rather than a linear sequence. Instead of 1–12, the dial is marked from 0 to 2π, reflecting the mathematical structure underlying angles, waves, and cycles found throughout physics, astronomy, and nature. A subtle rainbow gradient traces the full circle, reinforcing the idea of time as a continuous, harmonic loop. Designed for mathematicians, scientists, engineers, educators, and anyone who enjoys thinking differently about time, this clock functions perfectly as a standard wall clock while quietly teaching a deeper concept. • Radian-based time display (π notation) • Clean, minimalist mathematical design • Smooth rainbow circular gradient • Works as a normal wall clock—no learning curve required Ideal for offices, classrooms, studios, and thoughtful living spaces, this clock is both a functional timepiece and a symbolic instrument—inviting you to see time not just as hours, but as geometry.
