Clad in black, Patricia O'Donovan-Lockard sits cross-legged atop a big black box. In front of her is a small sand pit, behind her a couple of dozen puppets and props, within her reach the switches for all her lights. She is ready to tell the story of Louis Braille. A Touch of Light, from the Israeli Train Theatre, is simplicity itself, from the straightforward, expressive story telling to the purposely rough-looking handmade materials. At moments, like when young Braille dreams of his system of writing for the blind, it is beautiful, original, inventive, magical. At other times, it's that little bit drab and twee.

As shadow-puppetry, the play rarely achieves the heights of which the form is capable. But O'Donovan-Lockard has a good feel for childhood wonder and humour: yesterday, when the yellow pencils were lined up in the sand to represent Louis's schoolmates, the audience's appreciation was palpable in laughter.

For yesterday's performance, anyway, their appreciation was doubly palpable at the end, when half the hands in the house shot up to ask O'Donovan-Lockard excited questions about her preparation, her methods and Braille.
