tonic by reinhard dienes this is 'tonic', by reinhard dienes, a piece of furniture that can be either a standup bookcase or a low storage unit, by flipping the oak shell and moving the feet.

i thought the legs were maybe black rubber, but seeing the closeup shot (below) it looks like they are darker stained wood. i really like the contrast.

about the design, dienes says:

This transformation allows Tonic to adapt itself to changing living situations and desires.

im not sure how often the user might do this in reality, but it's still a nice idea.
