Simplified Quote from vid: "It shouldn't matter how much actual pixel data there is, only the amount that you see on your screen."
Dragonfly or something similar pops into my head when I think about it but I cant seem to find it anywhere. Pretty vague description but I cant remember much more about it.
.:Edit:. Nevermind I remembered where I found it. Heres a link to it for anyone that wants to see what I was talking about. Its called SeaDragon
