As others have discussed, making coding example images for the sole purpose of forcing them to type it out. Don't get me wrong, I copy/paste like the rest of us; however, from a learning perspective, I think forcing students to type out the code gives them practice, akin to how you'd practice your shots for basketball.

I've actually implemented typing exercises that are straight "copy this image" as one of the assignments I give students each week. Now, students have my lecture, the demo done in class, AND a typing exercise before trying to implement something like, say, a collision detection algorithm.
