A bench for temporal sampling and aliasing. One sampler drives a zoetrope drum and a strobed wheel; it is never given the aliasing law and recovers it anyway, to 2.13e-14 per second over 576 grid points. Measures every standstill and reversal threshold, shows that the drum rate cancels out of every ratio a zoetrope can produce, and runs the persistence-of-vision explanation to show it is time-symmetric and therefore cannot report a direction of motion. Independent reimplementation; the zoetrope is Victorian and out of copyright. Sources read in full are credited in CREDITS.txt, and the ones that could not be read are declared.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
