On looking at your image, I have to admit my "old computer knowledge" kicked in and I started wondering "Apple II graphics handling that? Perhaps..." Then, though, I got to thinking that saying anything more about the possibilities would risk making me one of those "Well, actually" people, and how one person's "Hmm, I'm curious" becomes another's "Good grief, nobody cares about all the useless trivia you've stuffed in your head." I did, though, decide I could put more of the pictures that caught my eye on my own Tumblr.
