Various knotted projections, each row determining a Reidemeister move in the shaded local circles (regions), and the middle projection in each diagram indicating singularities in the shaded circle.
There are three Reidemeister moves i.e. operations on a local region of a projection of a knotted curve. The middle local region in each row is the singularity each operation must pass through along with its corresponding color on the sphere.
Sketching the reality of the projections and the inaccuracies given by the shadows.
