I am far from being a graphic designer, but in my quest to help people learn about the great sport=candlepin I thought I might take a crack at making a couple simple icons. They're hand-crafted in Notepad and I've learned just enough SVG to be dangerous. I won't be offended at all if they don't end up being used. If you want me to make an actual PR I can probably figure that out but I figured I'd post them here first to see if they're the kind of thing you're looking for.
