This Demonstration shows an open view of an orthogonal projection for a flexible symmetric four-cube (tesseract) using Slavik Jablan's op art ornaments.

Details

To gain some intuition for the four-cube, consider the sequence where each figure is the extrusion of the previous one in the next dimension: 0D: point, 1D: line, 2D: square, 3D: cube and 4D: hypercube with 1, 2, 4, 8 and 16 vertices. A -dimensional polytope is bounded by cells of dimension : a square is bounded by four edges, a cube by six squares and a four-cube by eight cubes.

In this Demonstration one of the cubic cells of the four-cube is left out.

Victor Vasarely, the originator of op art in the twentieth century, made transparent sculptures similar to the figures shown here. Jablan Slavik constructed op art transparent four-cubes using black and white squares with a circular arc as a basic element.
