It is so cool!
If zoomed in, the effect is les pronounced.
I wonder if it has to do with the colours, or maybe that the brain can only properly position one at the same time.
I also wonder if the 'jumps' are the same length in younger and older people, or the ones with eye problems.
I also notice the blue one is already choppier than the yellow one, maybe the colour of the bars is crucial as well. Would it be less jumpy with white and grey, for instance?

@pascaline @bit101 it's the contrast. If you have a hard time distinguishing yellow from white on your screen, yellow will appear to barely move while the front overlaps white and then as soon as it overlaps black, it'll appear to snap forward. Conversely with blue. But it's also the differential between light and dark side by side. If you cover the yellow or the blue block and only look at the other, the effect disappears I guess the eyes don't have enough dynamic range to accurately process both brightnesses at the same time?
