I got inspired by the starfish, so I started my research by drawing all the parts of its body. The starfish has a water vascular system. It means that it uses saltwater to circulate inside its body to move its feet.

Maquette and mold

I started by creating a paper maquette and then moved on to a sturdier material to create the mold shape.


I covered the shape with silicon thick enough. Then I applied the fiber glass and forton on the outside to create the shell. Now I had the mold to cast the shade of the lamp in resin.
