There's some real magic to keeping things simple. Sometimes just the repetition of a single shape, over and over, results in beauty. These lights from Tel Aviv's Studio Mesila incorporate a variety of found artifacts. The designers assign a percentage to each product, indicating how much of the item is recycled.
My favorites are the button lampshades, which have such great sentimental DIY possibilities. Imagine making this from that jar of buttons your grandmother used to have, hints of the yesterdays when everyone sewed.
