This is a project about finding the seed of a Minecraft world visible in the "Skull on Fire" painting made by Kristoffer Zetterstrand in 2010, which was then included in the game itself. This painting was added into the game in Beta 1.3, even though the preparations for it (in the code) were already made in Beta 1.2_01 (https://minecraft.gamepedia.com/Painting). It was the last "true" painting added to the game. The wither painting, which is the only newer painting that has since been added, wasn't made by Kristoffer and wasn't based on any original painting. Yes, if you didn't know, all the other paintings in the game are downscaled versions of real paintings and they can be found in their full size here: https://imgur.com/gallery/R7qao. This can be found on Kristoffer's site here: https://zetterstrand.com/eventz/wp-content/uploads/skull_on_fire_framed_c_1910.jpg You probably couldn't really tell if there was a real Minecraft world from the in-game painting, but looking at this original version, you can see pretty clearly that it indeed is a Minecraft world. You might still doubt if it's an actual generated world, or if it was just something he randomly painted, but we'll get to that later. Spoiler: yes it's a real world.
Kristoffer is a Swedish abstract artist. His works are influenced by both classical and renaissance artwork, as well as computer graphics and 3D modeling. His website: https://zetterstrand.com/ He was a friend of Notch long before Minecraft was a thing. Notch decided he wanted to include his paintings in Minecraft, so he let Kristoffer downscale them (and edit some of them a little bit to still look good inside the game) and put them in the game.

At first, it was just an idea that I suggested in the #suggestions channel on our Minecraft@Home discord server.
It seemed to catch on, as at the time of writing, it's the most upvoted (stars) suggestion on there. The main motivation for this idea was the fact that it's the last legendary piece of the "Minecraft screenshots included inside Minecraft" trilogy (alongside pack.png & the original title screen background panorama), at least for the Java Edition, that is. There have been some other things added later, such as the custom world preset icons, or the newer panoramas, but those are not as significant. (We might still try finding them later tho.)
Looking just at the painting though, it would be basically impossible to get the correct perspective and block placements, since it's a hand-made painting, not a direct screenshot. We couldn't even know if the blocks are painted exactly as how they've been generated, that is, if it even was a real seed in the first place.
That's why I decided to reach out to Kristoffer and ask him for more details about the painting. Not sure why, but at first, I wrote a comment to him on Youtube, which despite being kinda stupid in hindsight, he actually replied after about 2 weeks and told me to contact him via email, which is probably what I should've done in the first place lol. Anyway, I then talked to him over email, to which he replied on August 21st 2020, and we got really lucky, because he actually still had the original screenshot!
