Spinning at roughly 1,500 RPM, the strips refresh 360 times per revolution to form 360 columns, producing a spinning cylindrical video display. A Hall sensor detects rotation speed and adjusts the refresh rate accordingly to keep the illusion stable regardless of spin speed. The creator says more demos may follow if there's enough interest. ## Full article daily.dev links to this article rather than hosting it.
