We investigate ways to determine the mood people are in through a simple interface, in order to be able to present a music playlist to them that fits the current mood and is possibly even capable of improving it over time. The relationship between moods and music is subject of research as well as colors and shapes. The combination of colors and shapes provides a solid estimation of the mood. We present a proposal for a Smartphone Application that includes these features and gives a great user experience with an innovative interface.
