Favicon variant

Same mark, restaged: the line drops to a stub so the bob can fill the frame. Top row is the standard mark, bottom is the favicon variant — the difference only matters below about 32px.

First draft

Section icons

Each one is the plumb line doing something — hanging true, hanging askew, sounding a depth, threading a seam. No generic gears or lightbulbs; the rule is that the icon has to be a pun the tool can actually make.

Sound familiar?

Taking a sounding — depths marked off the line

The through-line

One line passing clean through offset seams

The solution

Out of plumb, beside true

Keeping pace

It swings — and still resolves to vertical
