180 icons were commissioned for a variety of use cases, so an outstanding geological/industrial company could have a set of their own to match their identity. These are just a few.

The main limitation was that the icons needed to work at 16x16 px. Yeah I know right! Still, I designed them on a grid and checked the pixelation as I went. They all come off pretty well. Here's to creative constraints.

Pictographic

The hand was haaaaard. But I've never liked drawing hands.....
Symbolic 
Please note I was not aware of the actual context for each icon. I think this is to do with the work in progress nature of the project. But, I was happily surprised with how these icons looked in some preliminary screenshots from Fugro. In any case, very few of them are needing changes. 

Please keep in mind that the images below are from unfinished software.
