Students at the Copenhagen Institute of Interaction Design (CIID) created 'Twitter smoothies' using data from Twitter mentions of different ingredients. As the result of a data visualization course at CIID, Konstantinos Frantzis, Kat Zorina and Ruben van der Vleuten processed trending Twitter mentions of fruits and vegetables such as apple, carrot, blueberry and pineapple. They then blended smoothies based on the percentages of fruit flavors mentioned in the tweets, with an Arduino microcontroller controlling the flow of liquids. Because Twitter trends change quickly, each smoothie had a unique palette of flavors. While the experiment was just for fun, the students say the system could be used in future for brands to create 'Tweetsourced' products.
