on campuses. UniSA sport teams participate annually in both national and regional intercollegiate competitions such as the Australian University Games as well as the Southern University Games between Victorian, Tasmanian and South Australian universities. MOD. MOD. (Museum of Discovery) is described as "a futuristic museum of discovery". Its seven gallery spaces spread over two levels showcase science in a series of annually changing exhibits. One major unchanging exhibit is the Universal Gallery, featuring "Science on a Sphere", which shows planetary data on a sphere, with the surrounding walls being touchscreens which can be used to transform the planets, sun or moon. Other galleries include the Lecture Gallery, the Street Gallery, the Arcade Gallery, the Gould Interactive Gallery and the Futures Gallery. Aimed at inspiring young adults' interest in science, MOD. is free to visit in the Health Innovation Building (UniSA Cancer Research Institute) or Bradley Building (Purruna Wardli), on North Terrace. The museum has won a number of awards for its interior design, exhibitions and events since 2018, and has been used as a venue for Adelaide Fringe events. Selected exhibits 2022: Ngapulara Ngarngarnyi Wirra (Adnyamathanha for "Our Family Tree") is an art installation commissioned by MOD. and created by UNSW technologist Angie Abdilla, artist Baden Pailthorpe and former AFL player Adam Goodes, in a project named the Tracker Data Project. The tree refers to a 500-year-old sacred red river gum, or wirra, that lives on Adnyamathanha land. The installation is based on computerised biometric data gathered by the AFL via a small device worn on Goodes' back when playing football over the years. Sounds were created by an algorithm that mixes recordings of the wind and Goodes' voice speaking in the Adnyamathanha language with his performance data, while a 3D scan of the wirra and Goodes' data were combined in a point cloud, resembling stars in the sky.
