The Tragic Mouse Turns an iPhone Case into a Working Computer Mouse
The Tragic Mouse is an iPhone case that also works as a functional computer mouse.
It was created by Matty Benedetto of Unnecessary Inventions, a maker who builds deliberately unnecessary products. The creator's official page lists the device as operational.
Your phone already does so much, but apparently its case also needed to become a computer mouse. Now your phone has another job on the desk.
