In a post-apocalyptic world where aliens have taken over and nearly driven humans to extinction. Only one island remains safe and humans must find ways to disguise themselves. It was discovered that the aliens see clearly in infrared light, but can also discern color differences. Thus, camouflage technology has been developed to avoid IR detection as well as change colors.
This wearable machine curls up when the wearer is crouching, much like a roly poly's shell. It uses LEDs to change color. It changes color to camouflage against predators like the aliens that are hunting the humans. The plastic allows the color from the LED lights to go through but is still opaque enough where someone outside can't see through. It also camouflages infrared light because as long as the wearer isn't directly in contact with the material, body heat cannot be transfered and the wearer will be disguised from infrared detectors.
