Using a gear badge to represent customized code
The first one is an all white gear, the same used in "view source". The second has an outline, that may work better in general for any activity icon.
The following needs to be done programmatically:
- reduce activity icon by 71,43% (that reduction makes strokes of 3.5 pixels look as 2.5 pixels)
- put activity icon on the top left corner, with a margin of 2 pixels
- put gear badge on the bottom right corner, with a margin of 2 pixels
- I think you can add a border without changing the shape of the gear itself as per the example below. --Walter 12:54, 12 August 2011 (EDT)
