Artist Ho Siu-kee explores the physical and the intangible

For two decades,conceptual artist/sculptor Ho Siu-kee has been using one very important medium for his work — his body.

Whether it's Walking on Two Balls (1995), Gravity Hoop (1996) or his ongoing Aureola series, he puts himself into these experiential pieces, or performances — some require him to hang upside down, for example — to heighten his senses and spatial awareness. "I wanted to revisit and experience sensations that I might have forgotten since I was a young child," the 51-year-old says.

But Ho's artistic practice is taking on a new direction, shifting focus from the physical to the spiritual. This change is evident in his latest solo show, "Body Geometry", comprising four works that are scientific yet ephemeral and philosophical.

"My early works focused a lot on the bodily experience, but this awareness of the body, the physical practice, has led to realisation of the spiritual," says the artist, who practises qi gong. "It may have something to do with getting old; although I'm very busy, internally, at the core of my being, I'm seeking the spiritual, the peaceful state."

Ho says that after focusing so much on physical existence in the past, he became aware of the limitations of the human body — a realisation expressed in his work The Constrained Body (2008) — so now is the time to venture into an experience that is "beyond the body".
