That's ludicrous. You can get better scanlines by using Cathode or Cool Retro Term, and the latter comes with the beautiful 3270 font that stands upon the long clean design heritage of IBM's 360/379 line. This beautiful font, by the way, you can take for a spin on any civilized operating system by simply typing `apt-get install 3270font`. Go, try it.
