During the Olympics, Studio NAND, Moritz Stefaner, and Drew Hemment tracked Twitter sentiment with Emoto. This interactive installation and data sculpture is the last leg of the project.
The emoto data sculpture represents message volumes, aggregated per hour and sentiment level in horizontal bands which move up and down according to the current number of Tweets at each time. This resulted in simplified 3-dimensional surfaces which allows visitors to identify patterns in message frequency distribution more easily. And while not being specifically designed in this direction, the surfaces also nicely support haptic exploration.
The sculpture itself is black and unchanging, and it's used as a projection surface to display a heat map and overlay text. The projection is controlled by the user, which makes for an interesting blend of physical and digital.
