Japanese car maker Lexus has exhibited a life-sized replica of its IS sedan, created from 1,700 laser-cut cardboard sheets. The "origami car" was built in London by a five-strong team of professional designers and modellers from specialist companies Laser Cut Works and Scales & Models.

"The seats took a few attempts to get just right and the wheels required a lot of refining," explained Ruben Marcos, of Scales & Models. "Once we could
see the physical pieces taking shape, we could identify where we needed to make improvements -- as with anything, there were some elements of trial
and error, but as we had all the resources we needed in-house, this made the changes easier to produce." Being mounted on its steel and aluminium frame
allows the car to drive.

The car was on show at the Grand Designs Live consumer exhibition in Birmingham, UK from 8-11 October. Earlier this year Lexus debuted a real-life Back
to the Future-style hover board, containing a series of magnets and the modellers used a digital 3D model of the IS, provided by Lexus, which was then
divided into a series of parts, such as the main body, dashboard, seats and wheels. These were then digitally rendered in 10mm-thick "slices" to provide
the two-dimensional profiles needed for the precision cutting of each of the 1,700 fully recyclable sheets of cardboard.

Each layer was given its own reference number to ensure it was assembled in the right sequence and the car was then hand-built over a three-month period.
The cardboard cut-out car has a replica interior, functioning doors, headlights and rolling wheels. An electric motor superconductors cooled by liquid
nitrogen. It was able to levitate -- not unlike Marty McFly's hover board in the 1989 film Back to the Future Part II. - source CNN
