I read an article today on about a project that a Spanish designer named Cristina Ferraz Rigo did at the Royal College of Art. Her project was called “(DE)light”.  For this project, she created liquids that would glow- illuminating objects that they were in.
I enjoyed reading about the future implications of the idea. At first it reminded me of those glow sticks that we all play with when we are little. They have a similar idea, using light as a liquid. However, reading Rigo’s ideas, she said that she “was curious about the fact that domestic lighting has not changed…since Edison’s invention”. She was speaking about the fact that you always need a power source and a physical device.
This also reminded me of some MIT projects in which they incorporated pieces of the background into our everyday lives. They looked at new ways to modify objects.
