I very recently posted this comment over on the 3pointD blog (Link):

I’m waiting for aircraft structural components that look like bird bones whose cross-sections are both beautiful and amazingly efficient. Those could only be “grown”.

I’ve been interested in bird bones for a long time; ever since seeing a microscopic photograph of a its interior structure. So I was pleasantly surprised to see these Bone Lamps over on the Inhabitat blog (Link). They’re a long way from being rapid manufactured, but they’re still nice.
