Most companies seek out the latest displays for high-tech billboards, but Forever 21 has decided to take a different route for this particular Instagram project. For the past year-and-a-half, the folks at connected hardware maker Breakfast New York have been building a "Thread Screen" for the company. It's called that, because well, it's literally a screen made of 6,400 mechanical spools of multicolored threaded fabric. Those spools have five-and-a-half feet of fabric each, divided into 36 colors that transition every inch-and-a-half. They move like a conveyor belt, stopping at the right hue based on what picture they're displaying -- an infrared even scans the finished product to make sure each spool is displaying the correct color.
