Trivia: When Tony is flipping through his father's notebooks, he comes across a sketch of an object that looks like a cube within a cube with lines connecting the corners. This object is called a tesseract, which is a three-dimensional model of a four-dimensional object. Or in this case, a two-dimensional drawing of a three-dimensional model of a four-dimensional object. This is a foreshadowing of The Tesseract, one of the Infinity Stones, which plays a huge part in several of the other Marvel movies.
