The Seagull Effect @ Zoo Roxy

Idle Motion consistently punch above their weight and they're not afraid to be ambitious. Their new play at this year's Fringe is The Seagull Effect: a quick sprint through Chaos Theory, the hurricane that hit Southern England in 1987, and how just the wrong word – or perhaps, the word not said - can have a catastrophic effect on a relationship.

The play has IM's trademark inventiveness: ingenious scenery created with the minimum of props, a lover's pas de deux, inventive staging that stretches the boundary of theatre, scenes that segue from the realistic to the symbolic, and, more unusually for IM, the use of video projections and soundtrack. The sections of documentary soundtrack are particularly powerful, as real people relate their personal experiences of the hurricane.

The explicit thesis of the play is that our lives are chaotic (in the scientific sense). It's laudable of IM to take on such a challenging theme, and the skill and wit of the company is displayed at every stage second. But the dilemma of designing a play around a scientific theory is how to reconcile the imposed structure with the demands of the heart. An emotional resolution is attempted by referring key 'butterfly wing' elements (such as an umbrella, frizzy hair) back in time to the first meeting of the lovers. But for me, the ending of the play didn't quite manage a satisfying conclusion.

To take the play's theme seriously, maybe this is because I watched it when the butterfly's wing happened to flap in the wrong direction.
