Today is the 40th anniversary of Earth Day. It's a day to think about the environment and the planet, and to appreciate everything it's done for us. How are you going to celebrate?

Here's what we're doing: We're giving away our Earthy Underground themes all day today! Yep, you can get this groovy, earthy theme completely free — but only for today. Choose the HTML Editor, Visual Site Designer, Shopping Cart Creator, or Form Builder version... or better yet, just download them all!

NOTE: These themes are no longer available for free, but you can still buy them from our Theme Store.

We hope you enjoy these themes and do your part to help the Earth Day movement!
