No I dont know if it is new or not but i doubt any pictures were posted here on ForgeHub about it. Looks puzzling.
Yeah, I ahve done this before too. Its very old, but very awsome, and hard. Good job for finding though!
This is not an easter egg, its a cool find but its just the code demo for the other side of that texture. If you watch the essentials video there is something about it.
This is really old in fact, and it's not an easter egg. Ever notice that you glitched out the level behind a place you weren't supposed to be? Behind the tower because Bungie didn't bother to put an actual texture there so they just left some code there.
