Rivers and Tides is a documentary about a man who immerses himself in the environment to tinker and build art from parts of nature. Andy Goldsworthy is a British sculptor, photographer and conservationist who creates site-specific sculptures and land art located in natural and urban contexts. He lives and works in Scotland, but travels to various locations for conferences and commissioned works. Materials used in Andy Goldsworthy's art often include brightly colored flowers, ice, leaves, mud, moss, snow, stone, sheep's wool, twigs and thorns. Try to use nature as a whole and not modify materials with man-made objects. His art includes spiral constructions of broken stones, leaves attached to float in the river, and stick oculi. Find a way to arrange the twigs like spider webs. It creates a spiral of rocks that fans out from a small base and then closes, a weight at the top holding it together to end up like a stone egg. As we watch him work, he enters a completely different world where he understands how things are coming together and how long it will last. He pushes the limits until it feels right...
