Interactive animation visualizes how 9000 RPM exceeds screen refresh rates
↗
Mattias Geniar built an interactive animation demonstrating that a 9000 RPM engine crankshaft, completing 150 revolutions per second, spins faster than a typical 60fps laptop display can render frames.
For engineers working with high-speed mechanical systems or real-time visualization, this highlights a fundamental perceptual limitation: standard display refresh rates cannot faithfully represent rapid rotational motion without aliasing or blur. The tool provides a way to slow down and inspect crankshaft geometry and firing orders across four engine layouts at 1/50th speed.

At 9000 RPM, a crankshaft completes 150 revolutions per second, exceeding a 60fps screen's ability to render each position.
The interactive animation includes inline-4, 60-degree V6, boxer-6, and flat-plane V8 layouts with correct crankshaft geometry and firing orders.
A time control allows viewing at 1/50th speed, where individual piston movements become visible.
