...What annoys me is how GIF's repeat over and over. It would be better if there was 3 or 4 second pause before repeating.
Kind of makes me dizzy if I stare at it too long.
The creator of the gif has the option to adjust individual frame rates. No problem in choosing a (say) 3500 millisecond delay on the last frame before they set repeat (which is also optional)
They choose not to just to make you dizzy ;-)
