I have been using Chromium in Ubuntu for the past two months or so and i am already loving it! Chromuim web browser, which even have flash support enabled, has changed by a huge margin, and definitely deserves your default browser status. New updates are coming almost everyday and we have already seen how to install Chromium in Ubuntu the right way. Now it is time to theme your Chromium in Ubuntu.
Apart from the default google themes available, now a bunch for third party artist themes are available for Chromium. Here are screenshots of few among them.
Mariah Carey Theme
Kate Spade Theme
Anna Sui Theme
Good Planet Theme
And many more. Just visit available themes page from your Chromium browser and theme Chromium for yourself.
