Carles and Jesus Bel are the designers behind Bel & Bel, a studio in Spain. Their design philosophy is centered around upcycling. They take old machines and parts, mostly from cars and scooters, and turn them into not only functional but also luxurious pieces of furniture.
Lately, they've done a lot with the old Vespa scooter--that iconic symbol of mod style. They've remade the bodies of classic Vespas into chairs. You can see more photos of these chairs at Design Boom.
I would also encourage you to check out the entire Bel & Bel website, which is filled with similarly clever and beautiful works.
