There is a windows equivalent of Dashboard. It's called Konfabulator. And before I get any mac nerds telling me how different Dashboard is, and how dare I compare it to Konfabulator - I don't care.
And it has a family guy RQG - well, at least it has Stewie - but he's my favourite character anyway.
You can download Konfabulator here.
You can download Stewie RQG here.
Enjoy!
