The F21 Thread Screen is a massive machine (200,000 parts, weighing over 1 ton) that re-created people's hashtagged Instagrams via 6,400 mechanical spools of thread. All live on the internet, all in real-time.

There are shockingly few brands that are utilizing Instagram's API to provide an interesting and new experience for consumers. The Thread Screen was designed to show the world the potential of what you could do with this platform.

From initial concept to build, a year and half passed, but it wasn't pedal to the metal the entire time. We had to find the right time in Forever 21's marketing schedule to launch, and as such, some months had more people working on it than others. The majority of the initial build and assembly occurred over the first 6-7 months, with the rest of the time being a lot of optimization, testing, learning, and fine-tuning.

The entire machine and experience was designed, coded, and manufactured from the circuit board up. Of the 200,000 parts (8 times the number in your car), only the screws and a handful of other small parts were not design and manufactured by the team. That meant creating custom colored fabric, turned and stamped wooden spools, injection molded chassis, stepper motors, PCBs, wire harnesses, facade, idlers, a massive aluminum superstructure, and so much more
