      It's probably the sane phenomenon that makes wheels appear as if they are moving in reverse even though they're going forward

              Why not just make it 0 frames per seconds that would make it still too

                          This is incorrect or at least not accurate: the camera could also take a frame every time the rotor rotated 72°x2 or x3 etc. Could be at least.

                            Seizure warning probably woulda been a good idea.

                                @Pleasantly Rusty Partially. One in the description, or a more blatant warning within the video itself before the strobe itself would have been better.

                                            fun fact: if a helicopter engine starts up, you can see - no matter what frame rate(even with your eyes)- that the blades start spinning in one direction, some weird flashing, moving in the other direction, slowing down, and all that again a few times until the rotor reached the normal rpm.

                                              I was able to produce something similar with a store bought LED flashlight, and Variable Frequency Drive (VFD) controlled Industrial Fan (impeller style fan) Motor. Since was able to adjust the frequency to 1/1000 Hz (between 0/60Hz), I was able to accurately match the LED's oscillation so that the fan looked stationary at multiples of the resonance (may be the wrong word, but it feels correct to me) frequency.
