Most GIFs are designed to loop continuously, which could be distracting in a PowerPoint presentation.

The laughter of the laugh-loop GIF is both infinite and inexplicable, it erupts over and over again, without reason and without end.

This GIF shows the results of an unprecedentedly detailed simulation of the intergalactic medium (IGM), the gas-suffused, dust-sprinkled space between galaxies.

The second GOES-1 weather satellite GIF loop shows the eruption in infrared. As you can see, an eruption of this scale will spread pretty quickly throughout the surrounding states.
