That is the ender dragon needed for the boss bar at the top There are also horses at any holographic text field.
The same.. and if I touch it, the whole screen becomes code and stays that way. I can see the grass but it's got moving letters and numbers all over. It's still showing it... it's like numbers and letters are flying to this hole in the world.
it's in off topic because it's on single player. I haven't seen this show up on the multiplayer server.
Maybe Notch wants to tell us something in his code. Omg... thats so intense. a secret. Naaa i am just kidding.
Courious... What mod pack is this in? Yes i know out it's in single player. Is it just a random happening, our can you recreate it?
I saw one of those last week, and saw someone get sucked into it, wasn't a really nice sight (ps, this wasn't ingame)
does the modpack your playing on have thaumcraft? if so it might be an aura node of some sort possibly a hungry one
