An idea for the final product could be a scarf or something similarly large scale that had LEDs sown into it at regular intervals. This would allow you to run animations that would read differently if you were wearing it loosely, tightly, had it wrapped up around your face, etc.

For a project like this you would need:

- A scarf

- At least 80 individual LEDs, but likely more depending on the size and resolution of animation you want to display

- several small microcontrollers (many if you are using gemmas) that could be hidden or sewn into the scarf

- a portable power source (ideally something like a powerbank but batteries could also work.)
