The Rat Terrier

After building a few of the WASD Palm Controllers (The Pug), I realized that the form factor would work well as a mouse. 

The three buttons are your left, middle, and right click. 

Simply plug the box in via USB-C, and it will register as a generic mouse. This means it's compatible with computers and anything else that supports keyboard and mouse, like Fortnite on PS4.

While this particular version doesn't have the palm dome, I can make one in just about any shape you can think of, including a tall, arcade-style joystick.
