Blue Light Bulb Pillow

This simple design is inspired by old type of incandescent light bulbs, those smart devices that can produce light from electricity :) First incandescent lights were made in the early and middle 19th century and are the type of light bulb that Thomas Edison spent so much time on in the 1870s. It was the first light bulb that could be used in houses because of its low costs and sufficient reliability. It was bright enough that people could work and read easily at night and because of that It was used to light stores and streets so people could travel around after dark. This invention really changed the world.
