I'm posting this to be humble.
If I weren't humble, I would post this to Facebook or something where people could see it. So playing Minecraft, there's a newly added end game section to the game. Where you can actually beat the thing rather than an endless sandbox. Well, to get there you can track Eyes of Ender, which are silly things that you throw into the sky that fly up and land towards the Fortress, where you might be able to get to the end part. I realized that you can just triangulate the position. After two throws at P(-32,-198) which ended at P(-22,-198) and P(-250,-1556) which ended at P(-241, -1546) I calculated the position at P(972,-198). We went there, dug around, and found the sucker at P(1070,-101). The important bit being that we found the sucker. Seriously, there's so much space in the game and I found the sucker with math. When used right, Math is like a super-power.
