About it
A hypercube, or tesseract, is a cube in four dimensions. A square has 4 corners and a cube has 8; a tesseract has 16 corners and 32 edges, and its sides are 8 cubes. We can't see four dimensions, so this splash shows its shadow in our three: a cube inside a cube, with their corners joined.
At rest it rocks gently in 4D. Tap it to turn it once around through the fourth dimension: the pink inner cube swells out to become the outer one while the blue one folds inside, then it turns on back to where it started. Every edge stays perfectly straight the whole time. The 4D turn slider changes the strength of its gentle resting rotation, and Colors picks a theme.
