15 / 25·Motion & Interaction
PULSE
Cardiology exhibition. An exhibition that beats at your chosen rate.
About the work
A museum exhibition on the human heart whose monitor draws a synthesized ECG — five gaussians for P, Q, R, S and T — with a sweep-erase trace like a real bedside unit. A BPM control re-paces the whole page: the wordmark, the copy, the pulse.
How it was made
The waveform came from reading real ECG morphology, then tuning gaussian widths until a cardiologist would nod. Iteration went to the sweep bar's erase width and to easing the page's pulse so 40 BPM feels calm rather than broken.
Like every work in the exhibition, it passed three full iteration passes — a visual critique, a deepening pass, and a QA pass at 390px with reduced motion and zero console errors — and documents itself in its own build guide.
