I thought this was an awesome project. Estudio Guto Requena, in collaboration with D3 has created the Love Project. The project used brainwaves of a person who was telling their story of love, and turned those brain waves into complex 3D prints, unique to each individual. The pieces were printed in a variety of materials including glass, ceramic, ABS, PLA, and metal. More details on this project can be found here: http://3dprint.com/12300/3d-printed-love/

Check out one of the 3D printed pieces, depicting one individuals brain waves of love below. The are now trying to create a mobile application which can do somewhat of the same thing.:
