WISZSIM must be a true 180-degree rotational ambigram. The exact same glyph system must transform W↔M, I↔I, S↔S and Z↔Z. The word must remain legible as WISZSIM after a precise 180-degree rotation. Do not mirror, distort, or merely create a symmetrical logo. Design custom glyphs rather than using a conventional font. The W and M must be two rotational states of the same glyph. S and Z must remain legible after 180° rotation. Voir plus
