This isn’t something you can buy for your superyacht, but it is something you should experience. The Japanese conceptual artist Yayoi Kusama has created this space (full name: ‘Infinity Mirrored Room — The Souls of Millions of Light Years Away’), with mirrors, hanging spots of light and a floor in water. The effect is thrilling, disorientating, unique and thought-provoking – the three-hour queues before Christmas at the David Zwirner Gallery in New York are testament to that. Every home should have one.
