Daily Pattern: Screw

If I ever have to use screws in a project, odds are I can calculate how many holes there will be at the end of the project by using a little math. For instance, if I need to screw in one screw, it will probably take at least three trial-and-error holes before getting it right. So if I need to screw in four screws, I'll end up with about sixteen holes. Not so good for 3D projects, but it worked out fine for this 2D one.
