Orkut has just released a new theme for New Year 2009. I just noticed it now when I logged into my Orkut account. I was looking for a theme for new year from the time when they released a nice theme on the occasion of Christmas.
You can activate this theme from themes tab. To go to themes tab just click on Happy Ney Year on top of your Orkut homepage.
So, just set this theme to give your profile a look of new year and this theme looks nice.
