The Transponder Node is a small, semi-realistic electronic device with a rugged, prehistoric aesthetic. It features a compact, geometric shape with a slightly curved back for ergonomic handling, and a flat front with a glowing, circular display screen. The body is made of a combination of metal and primitive materials, resembling carved stone or bone, with visible seams and bolts for a handmade look. The screen emits a soft, pulsating blue or green light, indicating its active state, while the surrounding casing has a rough, textured finish with subtle engravings or tribal patterns. The device is designed to be attached to creatures or objects, with a sturdy clip or strap mechanism on the back.
