How can I draw metallic bonds?

This may sound crazy, but in all my years of doing chemistry stuff, I've never seen anybody draw metallic bonds. The reason for this is because is a little unusual.

Metallic bonds involve all of the metal atoms in a piece of metal sharing all of their with delocalized bonds. This is different from (where no electrons are shared at all) and (where the bonds exist only between two atoms).

As a result, drawings of metals usually look like this:

OK.
