The Alien franchise is home to some of the greatest sci-fi tech on screen, one of which is the bulky handheld motion tracker. Builder W. Navarre replicated this classic prop in 1:1 scale with LEGO bricks, and it is incredibly detailed throughout. Small details such as wires of varying thicknesses, screw holes, and side key pad with slightly spaced out keys make his replica believable.
My favorite detail of course is the readout screen itself, with a mosaic of cheese slopes representing the distances from the tracker… or the aliens in the room with you. Remember to look up.
