Here is a kinetic sculpture by artist Anne Lilly. Like most of her work, the piece is made of machined stainless steel. Though the pieces are finely crafted and sleek, they are not motorized; they require the viewer set the piece into motion via a gentle touch.
From the artist's web site:
Kinetic sculptor Anne Lilly uses carefully engineered motion to shift and manipulate our perception of time and space. Her highly ordered and precisely constructed interactive sculptures move in strikingly organic, fluid and mesmeric ways. Employing opposing modalities -- analytical and intuitive, rational and emotional -- Lilly's sculptures elicit new connections between the physical space outside ourselves and our own private, psychological domain.
