From PopSci:
Louise Ma, a Brooklyn-based designer, has been exploring the visualization of one of our most pressing emotions in an ongoing project called What Love Looks Like. This video, the first in a six-part series, shows different kinds of relationships as different solubility of a liquid in water–the people that become a part of you, the people you'll always remember and those who don't matter at all.
Ma and her collaborators, Chris Parker and Lola Kalman, have posted two more videos you can check out here. One involves fire! What Love Looks Like, video one of six from Tangible Graphics on Vimeo.
