Two fishes are fascinated by a shiny course in the sky.
When the user’s hand gets closer to the sensor (distance or light sensor) a light on the back of the frame, much stronger, turns on more and more intense, backlighting the shape of a huge abyss monster predator who was generating the shiny source itself.
The small light is connected to a battery with copper tape after a failed attempt to connect it through conductive thread through the 3 juxtaposed plastic sheets that support the paper components of the abyss monster. This attempt necessary to hide the circuit through the shape and the patterns of the fish itself.
