French auto makers Citroen ran the C-Design competition to see what designers could come up with using nothing but Citroen car parts and their logo in the design.
The winner was Ognyan Bozhilov who designed the Citroen sledge, the main image featured in the gallery. It uses car parts which include the back seat of a C4 Picasso, steering wheel of a C3 as well as roof pillars and spoilers from two other Citroens.
Austrian designer Roland Kaufmann used a C4 alloy rim in his designer for a "drain-cover" concept, which won him second place.
The other stuff in the gallery (the tricycle, the red stairs, the phone receiver and faucets(?)are not identified by Yanko. But I am guessing they are more designs from the competition.
