Today on Marazion beach, near Penzance, with a view of St Michael's Mount, I've been working with children from a local primary school. We've been making up new names for colours, writing Richard Long/Hamish Fulton style poems and watching kite surfers skim the waves.

The sun's been glorious, wind grabbing the surf. The tide's progressively gone out, revealing the causeway to the mount and people walking across the sand. Tomorrow will be classroom based, but being outside invigorates how we look at things, tunes our senses and perception of all that's around us.

When the sun colours the sea it seems to fill the body with water and silver. And the beach is littered with the most beautiful stones. So much to look at, the kite surfer entertaining us all.
