This afternoon my son and I drove from Cambridge to Lode, a small village just north of the city. When we got there we made our way to the old watermill and I lobbed half a brick across a river while Max filmed me.
Earlier in the weekend my friend Matt Jones, co-founder of the social network site Dopplr, had made a significantly more strenuous expedition to Knowle Park in Hildenborough to leave a rock shaped rather like a flint axe-head in a field.
Matt and I weren’t just randomly littering the countryside, but making our individual contributions to the ‘Britglyph’, a project that will eventually be the most extensive work of public art ever seen in Britain, one that follows in the tradition of the White Horse of Uffington and the Cerne Abbas giant.
