The Idea is to use illuminated bottles as pixels, more precise the bottoms of the bottles. To use the bottles as pixels, we will wrap them into aluminium foil and attach one RGB or RGBW into each bottleneck. When you put the prapared bottles back to their boxes and tilt the boxes by 90 degree, you will look at an array of 4x5 bottle bottoms. If you prepare more than one box, you can arrange them to a display.
The idea for this kind of display is not new, during this project we will develop, document and share our own approach.
