Starting from the observations made during the first exercise, the students had to choose a digital platform and modify the visual elements of a graphical interface through a Firefox web extension. The goal is to problematize some aspects of the platform (such as gamification and the user attention exploitation) through a process of hiding, exposing or semantically hacking some elements of the interface.

1. Choose a digital platform
2. Think about how to alter the UI through the browser inspector or a mockup up
3. Describe what the extension will do in one sentence
4. Code the web extension starting from the boilerplate
5. Publish the extension and make it available through a one page website
6. Add a video which explains how the extension works

Tools: Github, web-ext, Mozilla Firefox

Observe (November 21–22 ). Observe, deconstruct and describe extensively what you see while you are performing an action on a digital platform.

Alter (December 5–6). Modify the visual elements of a graphical interface developing a web extension.

Reveal (December 19–20). Extract and visualize the invisible trackers that follow you in one hour of web browsing.

Re-publish (January 30–31). Analyse and re-publish data coming from a digital platform to renew our understanding of a phenomenon.
