Notes

* My solution shows a "hollow plus."

* The size of the plus is irrelevant. You get bonus points if you used the actual screen size to make a larger plus. I used two arrays of preset coordinates to ensure that the plus would be proportional.

* And give yourself bonus points if you plotted the proper ACS characters at the corners and intersections.
