XYZZY is an immersive film, designed for planetariums by New Zealand artists Jess Johnson and Simon Ward. It premiered at the Otago museum, sold out 14 shows in Melbourne and now it's back in Aotearoa for a short stint at the Stardome. It starts its run tomorrow and goes through until the 10th of December. To tell us more about the project artist Jess Johnson talks to Mark.
