I received an email from Feel VR recently, who kickstarted a direct drive racing wheel for the PC, and they shared a kickstarter their “friend” started called Pix: The First Smart Animative Backpack.
It basically looks like a game frame built into a Backpack but with a 16×20 matrix and possibly less power hungry LEDs.
The tech specs are there if you scroll down.
Those leds would want to be pretty durable since the bag is going to flex so much and have pressure on it from all angles.
