Since the flag in hole icon has turned out to be so popular, I thought I should try to draw a larger version of it to replace the larger site icon used in various places like the SE site list. I ended up with two versions, so I figured I'd post both here and let you folks vote on them, just like with the smaller favicons.
Here's the second one, directly based on the pixel art version (shown on the right for comparison):
This one does have a ball next to the green, but removing it would be trivial. I like the rendering at full size, but I'm not perfectly happy with the way it scaled down to 48 × 48 px (middle image); some hand-tweaking might improve the results. Still, I feel the combination of pixel art and the flag symbol does work pretty well to symbolize "code golf".
Also, for completeness, here's the original SVG code from which these were rendered. Alas, it's a bit verbose, since SVG doesn't really do loops::

(Yes, I could've golfed it down quite a bit, but I didn't want to do that at the expense of readability.)
