I'm not convinced that bas reliefs would work very well.
An eye is usually depicted with a pupil, since that is an obvious visual
feature of it. If you feel an eye though it is a circular bump on a sphere.
As for warnings about electicity, a lightning strike sign is of no use to
someone who has never seen lightning.
I am also reminded of some tests they did with pictures (with sighted
people), where many africans thought that a squashed flat picture of an
elephant (like a skin layed out) was more realistic than a sideways view
that we find preferable.
