What is the best static icon to represent "work in progress"? [on hold]
I have a list of human work task, which each row has an icon on the left side to indicate if the task on the row has already finish or still in progress. For finish, I have no problem with the icon design. But for work in progress, I feel no icon can represent what I mean. Some icon ideas I found on the internet:
- An icon of a worker with shovel shoving dirt. (But I found this is too complex and can't convey "simplicity", and maybe not too self-explanatory if I only use silhouette of it)
- An icon of three dots. (But for me, three dots can also meaning there's a message or an action is waiting to be engaged)
- An icon of two circular arrow pointing to each other's end. (But isn't this icon for "refresh"?)
- An icon of Apple's rotating in progress (busy) image. (But this is a static image, and that also has more computer work meaning than human work)
This is just my interpretation of those icons, which made me conclude those four type of icons can't represent my "work in progress" meaning. Do you have other suggestion? Or do you have different interpretation about these icons that they might fit my purpose?
