16x16 icons for a work-in-progress project

For one of the projects I’m currently working on, I”m constantly making new small icons for different UI elements (buttons, tabs, etc.). We are at the very beginning, but this icon set is starting to shape up and I’m wondering what will be the number of icons in the end.

This set uses a 16px icon grid — just as limiting as it should be for a commercial project. But the 8px grid is definitely waiting for its chance;)
