New Themes for Personalized Google Page

I had just signed into Google to view my personalized home page when I noticed a link on the upper right hand corner next to the "Add Stuff" link: a link to select a theme! This can only mean that Google has just introduced themes for personalized Google pages! Woohoo! So I checked it out and found that currently there are six themes (aside from the Classic theme): Beach, Bus Stop, City Scape, Sweet Dreams, Tea House and Seasonal Scape. There are indications that the themes (except for the Classic one) will change throughout the day according to the current time or weather which is why one has to provide city/state or zip code. The only trouble is that the setting appears to accepts US locations and zip codes only. I hope they'll start including international time zones soon as the themes do look great. In the meantime, I'm trying out the Tea Room theme which seems to be the most interesting one (i.e. cute).
