Liquid-filled mice
You know, we get so tired of the same old mice here at Engadget. Drab plastic. Solid. Boring. That's why we're migrating the entire operation over to these babies, whose derrieres are filled with liquid and little floaty things to distract our weary eyes from the trawling, trawling, trawling of the feeds. And it only makes us slightly nervous to co-locate embedded liquid so close to all of the electronic equipment we base our livelihoods upon.
