Installing your work in the Turbine Hall of Tate Modern is a sought-after commission. Given her chance, Yi has created a swarm of aquatic-inspired interactive balloons (“aerobes”), illustrating her interest in the way art and science interact. It’s pretty cerebral stuff, Yi’s representation of “humans and the ecosystems we live in”. As to the installation itself, the museum calls it “unforgettable”. In that vast hall, however, critics are less sure, one calling it “all a bit ho-hum”.
