This is one of the more wacky inventions to come about in recent times, and it exudes more fun than practicality. All you need to do is fill it with some hot java and plug it into any available USB port in your computer. Clicking is achieved by pushing the whole mug towards the table. I wouldn’t recommend anyone doing their work with this mouse while the mug portion is still filled to the brim with freshly brewed coffee. There is also the risk of forgetting that the Mug Mouse is connected to the computer via a USB cable, hence an accidental yank could result in you scalding yourself and dirtying that $500 suit. Not sure if this is vaporware or just a concept, but it is a pretty cool idea overall.
