Imagine Alice in Wonderland crossed with a Greek myth and you have something of the flavour of this piece of movable outdoor drama created by street theatre specialists Dot Comedy. This is essentially walkabout theatre in an enclosed space (a maze constructed from a plastic privet hedge), but it is extraordinary how both enclosure and context combine to up the intensity and dramatic impact of the experience.
Dot Comedy pull the threads together beautifully: depending on your age and inclination, you can view it as a bizarre and enormously entertaining game, or a meditation on the nature of loss (of either your way or your marbles); the sad man in a purple suit who keeps coming up and introducing himself is clearly suffering from amnesia.
The joy of this is that you can cast yourself as the central character in your own epic and take it entirely at your own pace. You can be Theseus in search of the Minotaur, who turns out to be an exceptionally noisome and dirty beast. Once in, the idea is to find your way out, although perhaps finding yourself is the point. How much you interact is up to you: you can simply watch as Peter, Jane and their parents indulge in a 1950s-style picnic with Tupperware and jolly skipping, or you can join in and see what happens. But take things slowly or you could find yourself ejected from Eden. Remember, the hedges have ears, and the woman knitting or the kindly gardener may not be all that they seem.
It's a great show, with plenty of room still for development - and the really amazing thing is that it's free.
