The day that Chrome announced its new logo, I decided to exercise my fledgling SVG skills and recreate it, since it seemed so appropriate for vector graphics. I never got around to sharing it, though, so here you go:
Like everything I do, the code itself is public domain or CC0, your choice. I make no claims on the logo, though - I suspect that's trademarked by Google. But if you need a browser icon for whatever reason, feel free to use this one.
This should also be really easy to remake into a Chromium or Chrome Canary icon as well. You just have to change a few colors in the gradient definitions, easy peasy.
