I’m unlikely ever to get a tattoo, but if I did, I incline to the armband type; and I just got an idea for one: a ‘Mercator projection’ of Escher’s hyperbolic fish. Instead of a circle, the horizon would be two parallel lines, with one straight line of fish through the middle.

The prominent white arcs in that print are not hyperbolic straight lines but equidistant curves. One such arc could become a straight line along the Mercator band, but off-center.
