How Does a Computer Mouse Work?

You've probably used a mouse today. But do you know how it works? In this video, we explore the inside of a computer mouse and see what exactly happens when you move your mouse around on a mousepad.

From posting this video, a few people have inquired as to how we got access to the Logitech cad files. In fact, the models were made by opening an MX Master 3 Logitech computer mouse, taking reference images, and then modelling everything in Blender. But being able to fool people into thinking that we used the actual cad models is rather delightful. Just goes to show how far some modelling skills and Blender's photorealism can go.
