This is another old project that I made a while ago. I have to admit, the idea itself is stolen from instructables.com and you can see that the outcome looks similar at first glance. But I wanted to take a different approach. While I really like the shoji-design, I wanted my lamp to be more solid and long-lasting. Besides, I preferred the size (and ratio) of the DIN-A4-format, so that I can easily replace the paper without trimming it first, in case it gets damaged or i want to change the color. It has a beautiful ratio (297 / 210 = √2). The length of the sticks within the frame are chosen in a way that the rectangular pattern on the frame also has a ratio of √2.
