People using Google Personalized Homepage would be well aware that you can add pages, read feeds and lots of other stuff. Recently the folks at Google introduced a brand new feature to make your homepage look even better, viz. Themes.
Come Halloween and Netvibes is ready with a brand new Halloween Theme. This one is very different from the other themes that Netvibes has because this is the first dark theme they have. Though there is a dark background one wise thing is that the modules still have a white background with black text making it easy to read.
