A selection of design material will be collected relating to each case-study. This involves installing apps, capturing screenshots, requesting media packs, downloading branding guidelines and related activities. For case-studies not directly tied to a company, this material could include iconography, illustrations, slogans or copy which are consistently used to communicate the particular algorithm in media contexts. This material will be analysed from a design perspective, examining how strategic decisions about form and content produce specific affordances and experiences. Algorithms are inherently performative, not static designs parsed in the lineage of media literacy (print, posters, etc). Particular attention must therefore be paid to dynamic behaviours, user journeys, informational flows and context-sensitive content. These performances are also precarious. Therefore of special interest are the outlier moments of instability which reveal the structural logics underlying the designed surface.
