Why a mouse?

I'd forgotten that mice (or mouses according to the directory) weren't always as liberated as this one!

In 1968, a man named Douglas Engelbart created this special tool to help people control their computers. It was a small wooden block on wheels, and there was a long cable sticking out of the back, kind of like a tail! One of the researchers helping Mr. Engelbart with his creation called the tool a mouse. And that was that!

Later mouse devices were curvier and looked even more like mice than Mr. Engelbart's first model, while some newer computer mouse devices don't look much like rodents at all!
