How to Make a Tesseract

1. Start with a point.
2. Make a copy of the point, and move it some distance away.
3. Connect these points. We now have a segment.
4. Make a copy of the segment, and move it away from the first segment in a new (orthogonal) direction.
5. Connect corresponding points. We now have an ordinary square.
6. Make a copy of the square, and move it in a new (orthogonal) direction.
7. Connect corresponding points. We now have a cube.
8. Make a copy and move it in a new (orthogonal, fourth) direction.
9. Connect corresponding points. This is the tesseract.
