[12] The resulting exhibition Gold Card Adventures (named after the yearly Travelcard that she used), took place at Piccadilly Circus tube station in 2005 as part of the Art on the Underground scheme.

[18] Her final major "data collecting" project was the three-year Tea Blog (1 January 2006 – 31 December 2008), for which she published online what she was thinking about every time she had a hot drink.

[19] In 2006, Harrison ceremoniously rejected her "data collecting" methodologies and entered into a period of self-reflection and re-invention in order to develop a "healthier and more outward looking practice".

[22] She has used a mixture of sculpture, installation and live performance to respond to the British culture she grew up in and its dominant political and economic systems.

[41] Motivated by her concerns about climate change and the need to encourage the use of less carbon-intensive transportation,[42] she aimed to popularise the idea of returning Britain's rail network to public ownership, following its privatisation in 1994, when Harrison was 15 years old.

[47] In 2013 she was invited by Caroline Lucas MP to sit on "The Future of Our Railways" panel at the annual conference of the Green Party of England and Wales in Brighton.

[48] On 26 April 2015, less than six years after its launch, the Bring Back British Rail campaign reached a milestone of 100,000 supporters on its Facebook page.

[50] In 2013, Harrison led the "Say NO to Tesco in Scotland" campaign, which began as a protest against the proliferation of small supermarkets in the West end of Glasgow.

[55] As an exploration of bureaucratic processes, over the last few years Harrison has been involved in the setting-up and running of a number of experimental and fully functional organisations and institutions,[22] including the National Museum of Roller Derby (NMRD), which she founded at Glasgow Women's Library in 2012.

On 14 June 2012 the NMRD was launched, by establishing the library the official home of the UK's first permanent archive of materials and ephemeral relating to this all-female, full-contact sport.

[58] In 2011, Harrison was shortlisted for the Converse/Dazed Emerging Artists Award with the Whitechapel Gallery, London alongside Gabriele Beveridge, Bruce Ingram, Samuel Levack & Jennifer Lewandowski and Richard Parry.
