Are you fed up watching the same old Yahoo Messenger (bright coloured) window popping up everytime you sign in? Its the time to give it a new look. Thankfully, someone has created a Google Talk skin for Yahoo Messenger! (Like Google Talk’s clean interface?)
Installing the skin:
- Download the skin from here
- Extract the contents of the zip and move it to C:\Program Files\Yahoo!\Shared\Graphics (default installation folder, change it only if you have installed Yahoo Messenger somewhere else)
Activating the skin:
- Run Yahoo Messenger
- Go to Messenger > Change skin…
- Choose Google Talk from the drop down menu and click OK
Though the skin was originally created for Yahoo Messenger 7, it works smoothly on Yahoo Messenger 8.1

Yup
Looks great.
