A series of four clocks displaying the time on spacecraft orbiting Earth. One hand ticks at the time on earth, while the other hand ticks at the time on the spacecraft, with the hands growing further apart over time due to the effects of general and special relativity. The clocks were first exhibited in London, and in 2020 will be exhibited at Cube Design Museum in the Netherlands, before an eight-year exhibition at We the Curious in Bristol.
