9000 RPM is faster than your screen refreshes

An author notes that 9000 RPM equals 150 revolutions per second, a rate faster than typical screen refreshes. He created an online animation showing four engine layouts—inline-4, 60-degree V6, boxer-6, and flat-plane V8—and explains how, at standard 60fps, the crankshaft appears as blur, while slowing to 1/50x lets a single revolution be seen step by step. The post promotes the PWAs tool collection and invites readers to try the animation.
