four frames from a clock that runs on heartbeats; click to make it race under a synthetic pointer — with the ghost pointer

— views · — likes

Brief

The canvas displays a circular clock face centered on the screen. A single hand rotates around the dial, maintaining a steady, gentle movement that pulsates like a slow heartbeat. This gentle rhythm is visible constantly. When the viewer clicks anywhere on the canvas, the clock’s movement dramatically accelerates, causing the hands to spin rapidly and intensely. As soon as the clicking stops, the hand smoothly slows back down, reverting to the initial, natural, rhythmic pulsing.

Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited

This sketch presents a serene yet responsive clock that embodies the tension between stillness and motion. The hand pulses gently like a heartbeat, maintaining a constant rhythm that draws the viewer's attention to its subtle movement. When clicked, the entire system responds with an intense acceleration — the hand spins rapidly in a chaotic spiral before gradually returning to its natural, pulsing cadence. The interaction is immediate and visceral: a single gesture transforms the quiet clock into a dynamic whirlwind of motion, only to yield gracefully back to its contemplative state. This simple interaction explores how a small user input can trigger a dramatic shift in behavior while maintaining a consistent underlying aesthetic.
