At present, I can't see any reason why the wriggley lines of the Civil Time
adjusted Azimuthal dial (a.k.a. Dali dial) should not apply to other types
of dial, thus eliminating the need for an Equation of Time plaque. Using the
Horizontal dial as an example, if the 12 o'clock line were to wriggle like
an EoT graph, then the user would just have to take the time reading at the
appropriate distance from the centre (point where style cuts dial face).
Using  the same argument, a wave line could be drawn for the other hours
too. If the lines don't start right at the centre, it would even be possible
to have two sets of hour labels for standard time and for daylight saving.

This ought to apply to other types of dial. Do such dials exist, or am I
missing something? If they exist, has anyone got URLs for pictures?
