In certain creations I like to use LEDs, small light-emitting diodes, to try to give a luminous graffiti effect. I wanted a more contemporary alternative to my creations, but this process given the disadvantage that it requires an electrical power supply, I opted for a battery-powered system but which involves regular changing.
This technique can offer enormous graphic possibilities for low energy consumption, there are a multitude of colors and even diodes that change color, we can thus create all kinds of decorations, both furniture and urban.
