Folding mouse does yoga
It looks good, but we don't know how well it will work

For years repetitive stress injuries have sent manufacturers scurrying to build a better mouse, often at significant expense. But Japan's Elecom has decided to take a zen-like approach and look inward for the answer. Which is why it came up with the "M-D13UR" (such a clever name), a wireless optical mouse that changes shapes to suit its owner's needs.
The folding design makes it easier to store, and it definitely looks good. We have just one minor issue: It doesn't look like anything that would fit comfortably in one's hand, either folded or supine. But not having actually held it ourselves, we'll keep an open mind. Besides, we don't know anyone else who has a mouse that can do yoga.
