What Is A GIF?

short answer, 

 a lossless format for image files that supports both animated and static images, long answer, the Graphics Interchange Format, better known by its acronym GIF, is a bitmap image format that was developed by a team at the bulletin board service provider CompuServe led by American computer scientist Steve Wilhite on June 15, 1987, and here are some from Texas-based motion designer Marcus Martinez, 

he creates rainbow-hued GIFs against solid back backgrounds,

  producing animated elements that explode, twist, and sizzle with extraordinary color,

 He started his own tumblr around four years ago after admiring the works of Admiral Potato, PI-Slices, amongst others, and in that time period has amassed over 45,000 followers, 

I keep trying to find where one ends and were it starts again.
