Roman Signer is an internationally acclaimed artist who works in sculpture, photography and video. He is most famous for his captivating time sculptures, which involve building, executing and recording the results of arbitrary experiments

His performances throw art and science together to capture the transformation of materials over a fixed period of time

Traditionally, sculptors have always focused on crafting physical material in three dimensions. Roman Signer's work explores a further dimension: that of time. As the artist puts it, his time sculptures investigate: "something that is going to happen, is happening or has happened. Or could happen"
