Currently, we have the Stack Exchange standard voting and badge icons:
What would it take (beyond someone with a great idea and some graphics ability) to get some cool/appropriate icons like they have at Bicycles.SE?
I believe graphic design elements like this are usually done when a site graduates from Public Beta to being a full site - that's the biggest part of that process. You also get a better icon and specific colors/background/etc.
From what I recall, they have some graphic designers on staff who propose a design when it's close to graduation time, and then we have an opportunity to provide feedback then. But that's months and probably years away. :)
I have zero graphic design skill, but what about a dovetail profile around the up/down arrows and a round saw blade (circular saw/table saw/miter saw) around the star? We could also have a 4- or 6-pointed star with some stacked dado chippers, but I wonder if that could be made to look abstract enough for newcomers to realize it's supposed to be a clickable star.
