Part 1: Reflections on the participant’s progress

The participants had the task to pretend to be an algorithm that finds patterns in other participants online data. Based on this data they designed an object for another participant. The object was 3D printed and send to the participant it was intended for. Here are some pictures of the results.


Part 3 : workshop – Blockchain for Designers

The goal of this workshop was to get the participants familiar with the usage of bitcoins and the blockchains. Lego pieces were used as bitcoins, one piece represented one bitcoin. All participants had a set of stickers in their own colour, which were sticked on the lego bitcoins in order to track the transactions. Participants had to trade different materials with lego bitcoins. In three different rounds they had different trading tasks. In each round two participants functioned as minors, who had to calculate all transactions and announce when a block is closed. In the first two rounds goods such as water, sheep, grains etc. were used as values to trade. In the  third round the participants were asked to use their own values.

Some examples of the values they were trading were: a kidney, a moral compass, DNA modification treatment, a clean slate, time, dinner, holiday, advice, different insurances, multiplyer, a free out of jail card…


Part 4: workshop – Discussion and Design Implications

In the last part the participants formed teams and came up with service ideas.
