- What is a tesseract? Let's explain the geometry of the tesseract, a four-dimensional cube, through a clear and detailed animation. | The Brain Maze

Tesseract Projection: a shadow of the 4-dimensional analogue to the cube, also called a hypercube or 8-cell. A tesseract(4D) is to a cube(3D) as a cube is to a square(2D). This piece of mathematical art is CNC machined from a solid piece of aluminum and anodized black- a representation, including perspective, of one possible shadow a hypercube could cast into 3D space. Multidimensional mathematics are often used in the formulations of physics, and visualizations such as this one help give insigh
