The hardest job in this project is keeping a car suspended in thin air, and hachiroku24 handles it with genuine tensegrity. Black cords run from the rear and sides of the DeLorean down to the edges of the base, while the car's inverted curved arm hooks into a loop of string held at the top of a transparent mast. Once the outer cords carry tension, the whole assembly balances and floats stably in mid-air.
Everything below the car works as a display base styled as a mini-diorama. It is built from ordinary plates and Technic bricks joined with pins, and an upright curved liftarm in transparent plastic rises from the middle to form the mast. A matching transparent curved arm is attached under the DeLorean chassis, giving the two halves a mirrored pair of anchor points.
The stand-out details are on the vehicle itself. It is modelled in hover mode, with the wheels folded horizontally and translucent light-blue discs set underneath them to simulate hovering thrusters. The rear thruster components are nicely detailed, and a Marty McFly minifigure rides along on a pink hoverboard.
My one wish is a building guide. The mix of folded wheels, curved liftarms, string loops and tensioned cords looks like a puzzle I would struggle to reverse-engineer from pictures alone, and a parts list would make the whole thing far more buildable for everyone else.
