Monolitt is an Oslo art exhibit created by Norwegian artists Syver Lauritzsen and Eirik Haugen Murvoll. The waist-high object identifies the emotions in tweets, matches the emotion to a predetermined color, and oozes that color in paint out of the top. It's like city-wide techno-mood ring. Only cooler than that description.

In the artists' video, you can watch both the building of Monolitt and watch it squirt pink with happiness and black with anger. From the artists' statement:

MONOLITT is an interactive installation that quite literally paints the mood of the city, using social media feeds as an input. The installation takes electronic signals and lets them manifest themselves in the physical world. Using sentiment analytics, the installation links tweets to corresponding colored paints in realtime, feeding them out through the top of the sculpture, letting them flow into a procedurally generated three-dimensional painting.
