Pretty useless, but I tried to replicate the way that a human moves the mouse on a computer. Unironically, I think I actually might have done a good job too, because this looks pretty convincing. Oh, and if you really want to make sure it's not just like, manually animated, or some kind of gif, you can see the script by looking at the project.
The script isn't really that complicated, all it does is a bunch of random stuff, as that's pretty much what a mouse cursor looks like. Oh, and if you press SPACE you can teleport the cursor to the center of the screen because I guess it really likes hugging the right wall for some reason.
