A word meaning "looking like the object that it describes"

Is there a word that means "the word looks like the object it describes"?

For example: "bed" looks a bit like a bed, with the b and the d acting as head and foot boards, with the e as the mattress. "Shark" Looks a bit like a shark, with the capital S looking like the tail fin and the k looking like the mouth.

Solution 1:

It is a type of iconicity.

The Wikipedia entry for iconicity currently begins:

In functional-cognitive linguistics, as well as in semiotics, iconicity is the conceived similarity or analogy between the form of a sign (linguistic or otherwise) and its meaning, as opposed to arbitrariness.

Solution 2:

I think it is a particular type of autological word, but I haven't come across a discussion of this type before, so I don't know a word for it.
