North / South / East / West
North / South / East / West: This ambigram contains shapes which can be viewed in four different ways to read four different words. This is much more complicated than the typical two-way ambigram. You need to rotate the picture (or turn your head) to see each word. This design uses a very odd kind of symmetry, which I call Ferris-wheel symmetry. It contains only four letter shapes: 1=n/S/E/W, 2=o/a/e, 3=r/u/s, and 4=T. Each of the first three letter shapes appears at four different positions: north, south, east, and west, but the shapes are not rotated as you might expect. These shapes remain right-side up, like the seats on a Ferris wheel. The fourth shape, the "T", also appears at four different positions, but it is rotated. The "H" is made from two "T"s. This is not as pretty and readable as other ambigrams, but most ambigrams cannot be viewed in as many different ways.
