It's IkeaHacker plus: Spain's Yonoh Studio issued a challenge for designers to view their local Ikea not as a retailer, but as a source of raw materials. The idea is to then design and build a new object using parts bought at Ikea. Seen above, a variable-height desk lamp made from a rag-hanging rack and a light fixture.
Entitled Surtido de Mutaciones (Assorted Mutations), the project's resultant objects can be viewed here. Unfortunately there are no captions, so figuring out what went into each piece will truly test your knowledge of the Ikea catalog.
