Now Paul he won't even get the joke if he is new. It I can see the temptation.
I sort of get it, I'm assuming those are lines of code that "point" to things. But besides that...

What sort of screen are you thinking of, arduino and graphics output are possible but it is normally low res stuff that does not look too cool.
Probably some kind of LCD character display, maybe something like this. I feel like these are my best bet for a combination of "cool" and practicality.
