I grew up living beside the sea. Many of my childhood memories have the beach as a background and I used to love playing in the sand dunes at Murlough nature reserve in County Down, Northern Ireland. Walking on the shore I could easily get lost in the linear patterns on the tide coupled with those on the beach. The almost tessellated rhythmic memories of the water left after the waves receded and how the patterns seemed to become part of a bigger pattern when looking from a distance, always fascinated me.
