GIFGIF

Tumblr oughta love this, part 3:

An animated gif is a magical thing. It contains the power to convey emotion, empathy, and context in a subtle way that text or emoticons simply can’t.

GIFGIF is a project to capture that magic with quantitative methods. Our goal is to create a tool that lets people explore the world of gifs by the emotions they evoke, rather than by manually entered tags.

This one’s another time-wasting-for-science project out of the MIT Media Lab. Ars Technica has more details.
