Dear Data, created by information designers, Giorgia Lupi & Stefanie Posavec, documents their lives for a year through a "slow data" transmission. Whilst living on either side of the Atlantic they both collected and measured a particular type of data relating to their lives every week, visualising the results on the back of postcards, which they sent to each other.
