In this project we will make beautiful pieces of art that can change their colour when you move them. We do this by using the phenomenon called polarisation – this is a property that light waves exhibit. So, in the end, you will not only use your creativity but also learn something about the physics of light! Besides, you will use a laser cutter, a 3D printer and many of the other handy tools provided in a Fab Lab.
