Nowadays, high pixel LED screen is the most popular media to demonstrate the graphics and design. We are thinking there should be a playful way to show our graphics other than using this high-tech lighting system. We design RGB Glass; RGB Glass not only satisfies our curiosity but also composes our graphic with light playfully. It is a collection of glass that interacts with programmed lighting system. It consists three different basic color graphics in disorienting image. The image is purely composed with RGB light, each layer under the image is being seen clearly through the coloured light.
