-The arcade cabinet runs [Intcode](9) software like the game the Elves sent (your puzzle input). It has a primitive screen capable of drawing square _tiles_ on a grid. The software draws tiles to the screen with output instructions: every three output instructions specify the `x` position (distance from the left), `y` position (distance from the top), and `tile id`. The `tile id` is interpreted as follows:

 This 5x5 grid is _only one_ level in an _infinite_ number of recursion levels. The tile in the middle of the grid is actually another 5x5 grid, the grid in your scan is contained as the middle tile of a larger 5x5 grid, and so on. Two levels of grids look like this:

 As you reach the bottom of the _relentless avalanche of machine parts_, you discover that they're already forming a formidable heap. Don't worry, though - a group of Elves is already here organizing the parts, and they have a _system_.
