Mahna Mahna (Do doo be-do-do)

I had a situation where I wanted individual nodes within a view to appear different from one another. (e.g. add additional spacing at specific places in a grid view, color code the grid for easy scanning, etc) To accomplish this, I tagged each node with a series of taxonomy terms associated with various traits.

Recently I developed a site for viewing switch maps. Basically, each switch was it's own node, each module within the switch was it's own node, and each individual port within each module was it's own node - all linked using node reference fields.
