A moth flew into the building halfway through The Palm House and fluttered around in the light and mist. I wasn't sure if it was real or part of the performance.

This is the mesmeric power of Small Wonder's site-specific show, which creates a world where rain falls indoors, white fire snows down outside and humans grow from the earth like saplings. In this new vision of reality it's easy to believe in a stage-trained moth.

The piece was created specifically for the airy glasshouse at Stanmer and it's hard to see it having quite the same effect anywhere else.

The audience stand on concrete paving round the edge of the space while the performers dance, roll and tumble across the stage of bark chippings n the centre.

The show was devised to represent the cycle of life and man's relation to nature. In the programme it sounds pretentious but it translates physically into a series of simple, powerful images which burn into the retina.

It starts at dawn with a gardener raking the earth. From that gentle beginning it rolls into a fantastic melding of light, music, pyrotechnics and human flexibility.

Dancers waltz through glowing palm trees; a girl steps through space on men's hands while flames roar at the windowpanes; women try vainly to beat away a deluge of raindrops.

Small Wonder and the World Famous fireworks company have put together a wonderful piece given deeper resonance by the dark reflections of the glasshouse.
