Google recently released an update to Personalised Homepages - however, only on the US servers it seems.

You can now set a theme :) Not a bad addition, certainly has the possibility of brightening up an otherwise dull page, however, would be even better if it was more customisable - and available on the UK servers.

For those that are interested, login to your personalised homepage, then visit www.google.com/ig - a new option will appear on the right hand side (Select theme).
