So, my Wireless Mighty mouse is an amazing mouse. Paid $79 dollars for it, so I wasn't going to let it die when the ball got all torn up after it's long term use. I didn't feel like cracking open my no longer used wired mouse to confiscate it's ball, so I looked for another solution. I found this small metal marble, the same size as the mighty mouses ball. I put it inside, put the mouse back together, and now I have a unique, working mouse. I posted some pictures, as I felt it looked cool, and thought i would share the idea with others.
