NeoPixels Revealed: Warping time and space to actually see inter-pixel jitter @ josh.com.

n the PWM article, we discovered that each NeoPixel has a clock that free-runs at about 500Hrz and each pixel will only update its displayed color at the end of a clock cycle. This means that there should be about 2ms of jitter when updating a pixel, which absolutely limits the maximum refresh rate.

This sounds good in theory, but how can we actually see something that happens over the course of 1-2ms?
