Luke Jerram, the artist who hung that model of the moon in the Natural History Museum in 2019 and has done the Earth at the Old Royal Naval College and the Kensington & Chelsea Festival, is back showing Gaia at the Landmark Arts Centre, as part of the new Arts & Ideas Festival in Richmond. The illuminated 3D installation, measuring seven metres in diameter, features detailed NASA imagery of the planet’s surface accompanied by surround sound from composer Dan Jones.
