My intravention is to create a “seaside gallery” in a natural environment, using the rocks of the seashore as a canvas to paint images of polluted seas or beautiful blue seas. Using the Edinburgh seaside as a practise destination—Granton Beach—the bright colours of the seaside will attract attention, and the content of the paintings will inspire reflection. I chose Granton Beach as my test site because it is not as blue and beautiful as the sea at Portobello Beach. People are always looking for the good things, getting so caught up in the visual beauty that they don’t see the bad things and don’t think about why the seascape is different when it’s the same coastline. So, the bright seaside gallery will be a contrast to the seascape next to Granton Beach. I also have a plan to organise a seaside painting event, inviting visitors to the beach and the neighbourhood to participate, where people can use colour to express their concerns about the sea and share their love of it with each other. The paintings left on the rocks will also create a beautiful sight that will visually attract the attention of people who are playing and walking on the beach, who I believe will be struck by the visual contrast between the colours of the seaside gallery and the reality of the ocean, and the content of the paintings will also call attention to marine pollution and marine life. These action plans will provide a participatory and performative dimension to the project. Another effect I hope to achieve is that the seaside is a popular place for people to play, but at the same time, people’s activities can also pollute the sea, and when people see the seaside gallery, I hope this will act as a cue or suggestion that people should not act in a way that pollutes the sea. The project started out on a small and local scale. When the Ocean Gallery project has had some effect and impact, it can be used as a model for future development on a larger scale, calling for people to spontaneously create galleries for the marine conservation movement, and the project will draw attention to marine pollution and marine life around the world, as well as reflecting on their own actions. Initially, I planned to create a colouring game—perhaps a colour contrast between the blue ocean and the polluted ocean—to draw attention to this. But this was far less effective than creating a direct interaction and connection between humans and nature in real life. As the project is planned, people are encouraged to participate in the rock painting, and the seaside gallery is spread throughout the beach. More than anything else, it is hoped that when people see the seaside gallery, it will lead to reflection and action.
