Just over a year ago, I had a bracing winter's walk on Crosby Beach where Antony Gormley's sculpture Another Place can be seen along a two-mile stretch of the sands. About 100 cast-iron replicas of the artist's body can be seen. They all face out to see but some are sunk deeper into the sand and some are closer to the sea. This variation adds interest to the beach walk.

What I like are the questions that spring to mind when you see this sculpture. It can be fun to simply stand beside one of the figures and look out to sea. What you are seeing is what the sculptures will see. It's a chance for children to stop, look and just be.

If you have ever read the book Papillon, the author escapes from an island where he is a prisoner by watching the waves. He realises that every 7th wave is extra big and has the power to pull him out to the ocean in the right tidal conditions. This possibility has stuck with me ever since. Is every 7th wave slightly larger than the rest? Is there any pattern to wave formation and landing on the beach?

The next time you find yourself in another place on a beach, check this theory out.
