Down To Earth is a great looking environmental WordPress theme from designer Plentong (which I believe is a town in Malaysia).
The theme boasts a beautiful featured post slider, drop down navigation menu and 2 custom widgets. It also comes packaged with unique page templates for a services, FAQ and news page. Although it’s marketed as an eco-theme, I think it could easily be used for a number of niches.
A single license for Down To Earth retails for $25 from ThemeForest. The download includes documentation on how to use the theme and original photoshop psd files too.
