Although Google Chrome does not officially support themes, it’s possible to skin the browser by editing the various elements of it’s GUI. The good part is, all GUI elements of Chrome are stored in a single file called “default.dll” under the directory C:\Documents and Settings\USER\Local Settings\Application Data\Google\Google Chrome\Application.
Update: Try this alternate online Chrome theme creatorThis DLL file can be edited using Chromium Theme Creator to create your own themes. Of course, you will still need to design the various buttons and other components using an image editor. Chromium Theme Creator makes this easier by allowing you to directly load any image from the default theme to your preferred image editor. After you have edited the image, save it and the change is immediately reflected back on Chromium Theme Creator.
This way you can edit each and every element of the GUI. At first, this may seem tough and might take a long time to achieve the desired look but with practice you can make even complex changes to the interface.
The software also comes preloaded with a handful of different themes. Then there is always the Internet where you can find more.
